First one: 3×4÷2
Since multiplication and division have the same power, you do the equation in order.
3×4=12
12÷2=6
Second one: 4+16-10
Since addition and subtraction have the same power, you do the equation in order.
4+16=20
20-10=10
Third one: (1+2)+3×4
You have to do the parentheses first...
1+2=3
Now you have to do multiplication since multiplication goes first (according to PEMDAS)
3×4=12
Now you have to add (3) and (12)
3+12=15

Describe the process you would use to find the solution to the problem 3 1/4 minus1 1/3. Express your answer numerically and with a graphical representation.
Answer:
1 11/12
Step-by-step explanation:
Notice (right away) that the denominators of the fractions are different (4 and 3).
Identify the LCD: It is 12.
Convert the two given numbers to mixed numbers with LCD 12:
3 3/12
-1 4/12
-----------
4/12 is greater in magnitude than 3/12, so we must 'borrow' from the digits' place. Recall that 1 = 12/12.
Then 3 3/12 = 2 15/12. -1 4/12 stays the same; it has LCD 12.
Then, perform the indicated subtraction:
2 15/12
-1 4/12
------------
1 11/12 (answer: this is the difference "3 1/4 less 1 1/3")

What is the equation of the line that passes through the points (15, 9) and (Negative 2, 9)? y =
Answer:
y = 9
Step-by-step explanation:
We notice that both points have a y-coordinate of 9. Since they are the same, the equation must be y = 9 because the function can't "dip" or "rise", otherwise it would be a piecewise function and not a linear function. The equation y = 9 basically means that no matter what x is, y will always be 9.
Answer:
y = 9
Step-by-step explanation:
First find the slope of the line. As we go from (-2, 9) to (15, 9), x increases by 17 but y does not change at all. Thus the line is y = 9, good for all x values.

l + 4 = 2w => l = 2w - 4
5w + 6 = P => 5w + 6 = 2w + 2l
5w + 6 = 2w + 2(2w - 4)
5w + 6 = 2w + 4w - 8
6 + 8 = 6w - 5w
w = 14
l = 2x14 - 4
l = 28 - 4
l = 24 cm

Answer:
You would do the division first.
256 / 16 = 16
so, we have to determine 80 -16 +8
equals 72
Step-by-step explanation:
Answer:
The answer is 56
Step-by-step explanation:
To answer the equation, you must do the order of operations. Which is PEDMAS.
P= Parenthesis
E= Exponents and Radicals
M= Multiply
D= Divide
A= Add
S= Subtract
Always multiply, divide, add or subtract from left to right.
Because the equation is: 80 - 256 ÷ 16 + 8.
Your equation should be:
80 - 256 ÷ 16 + 8
= 80 - 16 + 8
= 80 - 24
= 56

Norma has a credit card that uses the adjusted balance method. For the first
10 days of one of her 30-day billing cycles, her balance was $1850. She then
made a purchase for $160, so her balance jumped to $2010, and it remained
that amount for the next 10 days. Norma then made a payment of $930, so
her balance for the last 10 days of the billing cycle was $1080. If her credit
card's APR is 29%, which of these expressions could be used to calculate the
amount Norma was charged in interest for the billing cycle?
The solution is : The amount Pearl was charged in interest for billing cycle = $19.8
What is interest?Interest is the price you pay to borrow money or the cost you charge to lend money. Interest is most often reflected as an annual percentage of the amount of a loan. This percentage is known as the interest rate on the loan.
here, we have,
Starting balance of Pearl for first 10 days of her 30 days billing cycle =$1120
Purchase made = $ 340
Total Balance after purchase made = $1120 + $340
= $1460
Payment made after 10 days = $580
Balance for last 10 days = $1460 - $580
= $880
Credit Card APR = 27% Annually
Credit Card APR = 2.25% monthly.
Amount charged as an interest for billing cycle = 880 × 2.25%
= 880 × 0.0225
= $19.8
Hence, The amount Pearl was charged in interest for billing cycle = $19.8

Solve the inequality |x+3| - 2>9
Answer:
x < - 14 or x > 8Step-by-step explanation:
|x+3| - 2 > 9
First add two to both sides
That's
| x + 3 | - 2 + 2 > 9 + 2
Simplify
We have
| x + 3 | > 11
Apply the absolute rule
That's
If | u| > a where a > 0 then
u < - a or u > a
So we have
x + 3 < - 11 or x + 3 > 11
For x + 3 < - 11
x + 3 < - 11
x < - 11 - 3
x < - 14
For x + 3 > 11
x + 3 > 11
x > 11 - 3
x > 8
Combine the intervals
We have the final answer as
x < - 14 or x > 8Hope this helps you
Answer:
x > 8 ∪ x < -14
Step-by-step explanation:
Start by adding 2 to both sides, obtaining the simpler inequality
|x+3| >11
Rewriting this as | x -(-3) | >11 makes the solution easier to visualize. Think of (or draw) a number line with an open circle at x = -3. This is the "center."
| x -(-3) | >11 tells us that x is either 11 units greater than -3 or 11 units smaller than -3:
x > 8 ∪ x < -14

Proportional relationships, please answer all of the parts! Thank you!
Answer:
a. No (see below)
b. (see below)
c. Johnny
d. Johnny = $12.50 / hour Doug = $9.16... / hour
e. Doug: extend the table to show how much he gets paid for 1 hour of work (the unit rate)
Johnny: already on the graph
Step-by-step explanation:
a. No. This is because a proportional relationship would have a certain ratio between payment and the amount of time spent working, which would not change. However, if Doug's neighbour pays him $55 for 6 hours, it's likely that this is not a proportional relationship, or we would be able to divide $55 by the 6 hours Doug spent working.
b. Even though above I said that it's probably not a proportional relationship, if it were, we would have to divide everything equally. I'm guessing the table should look like this:
Doug
Time (hr) Earnings ($)
4 $36.66...
5 $45.8333...
6 $55
7 $64.4666....
8 $73.333...
To work out how much Doug would get for working 4 hours:
4/6 x $55 = 2/3 x $55 = $36.66... (so definitely not a proportional relationship)
To work out how much Doug would get for working 5 hours:
5/6 x $55 = $45.8333.... (more evidence that this is not a proportional relationship)
To work out how much Doug would get for working 7 hours (we already got 6 hours):
7/6 x $55 = $64.4666...
To work out how much Doug would get for working 8 hours:
8/6 x $55 = $73.33... (we could double the 4 hour payment, but this is probably more accurate)
c. Johnny is getting paid more. If we look at how much Doug gets for 6 hours, it's $55. If we look out at how much Johnny gets for 6 hours, it's $75. (If we do the same with the other amounts of time, it's the same.
4 hours: D = $36.67 vs J = $50
5 hours: D = $45.83 VS J = $60
etc...
d. Johnny gets $75 per 6 hours --> 75/6 = $12.50 per hour
Doug gets $55 per 6 hours --> 55/6 = $9.1666... per hour
e. Carry on the table for Doug all the way to 1, so you can see the how much Doug gets paid for 1 hour of work (i.e. the minimum).
The unit rate is already on the graph for Johnny.

Answer:
The third answer. ( John's boat was farther from the deck at the beginning but Roberta's boat traveled more quickly)
Step-by-step explanation:
You already know that in the beginning John's boat begins 20 miles from the dock. Now you need to find Roberta! When each boat begins from the dock, it means when x=0. So lets insert that! y= 6(0)+15. You get 15. Now you know that its either the 3rd or 4th answer. The second piece of info you have for John is that it is 45 miles from the dock after 5 hours. Again, in the beginning it started with 20 miles. 45-20= 25 miles TRAVELED in 5 hours. For Roberta, we need to insert 5 in the equation for x. y=6(5)+15. You get: 45 again! But... Roberta started at 15 miles. So 45-15 is 30 miles. She traveled 30 miles in 5 hours. The only answer that is matching to our problem solving is the third answer. Hope this helps!
Please help! I suck at math ;-;
Answer:
x=80
Step-by-step explanation:
because all lines intersect at point E, we could safety say they are equal. therefore, we can also say that angles aef+def=ceg+beg.
we already know what ceg+beg is; 160 and we also know what def is, which is 80.
we set up an equation plugging it in. we will say ceg=x.
x+80=160, subtract 80 on both sides and you get x=80!
hoped this helped :)
The Painter siblings, Elsa, Ben and Cal paint houses. They have been in the business so long that each knows exactly how many square feet each other paints in one hour and these rates never change. For their latest job, they calculated that if Elsa and Ben did the job together, it would take exactly 11 hours. On the other hand, if Elsa and Cal did the job together, it would take exactly 9 hours. Finally, Ben and Cal could do it in exactly 9.9 hours (or if you prefer, 9 hours and 54 minutes). They decided all three would paint this particular house. Ben and Cal started the job at 8 AM and Elsa joined them at 9:00. Cal left at 1:30 and so Ben and Elsafinished the job. After deducting the supply costs (paint etc.), the brothers split the net profit based on what percentage of the total square footage each painted. Who earned the most and who earned the least for this job?
Answer:
Elsa earned the most
Ben earned the least
Step-by-step explanation:
E = Elsa's speed
B = Ben's speed
C = Cal's speed
The combined speeds are:
E + B = 1/11
E + C = 1/9
B + C = 1/9.9
If we add up all three equations:
2B + 2C + 2E = 10/33
B + C + E = 5/33
If we subtract each of the first three equations from the total equation, we can find the individual speeds.
C = 5/33 − 1/11 = 2/33
B = 5/33 − 1/9 = 4/99
E = 5/33 − 1/9.9 = 5/99
Ben and Cal paint together for 1 hour. The fraction of the wall they paint is:
(1/9.9) × 1 = 10/99
Elsa, Ben, and Cal all paint together for the next 4.5 hours. The fraction of the wall they paint is:
(5/33) × 4.5 = 15/22
Ben and Elsa then finish the job. The amount of wall left is 1 − 10/99 − 15/22 = 43/198. So the time it takes is:
(43/198) / (1/11) = 43/18 hours
The fraction of the wall that Ben paints is:
(4/99) (1 + 4.5 + 43/18) = 284/891
The fraction of the wall that Cal paints is:
(2/33) (1 + 4.5) = 1/3 = 297/891
The fraction of the wall that Elsa paints is:
(5/99) (4.5 + 43/18) = 310/891
Answer:
Ben earned the most as 6 of 16.5 as a percentage = (6*100):16.5 =36.36%
We check with Elsa and she earned the least as (5*100):16.5 =30.31%
Cal earned the average as 5.5 of 16.5 as a percentage = (5.5*100):16.5 =33.33%
Step-by-step explanation:
E + B = 11hrs
E + C = 9hrs
B+C = 9.9 hrs
Lets say the house was 100ft sq
if E took 5.5 hrs
B took 5.5hrs we would have 11
C took 3.5 hrs we would have 9hrs for E+C
B took 5.5 hrs + 3.5hrs we are 0.9hrs short and see that B would need to take 0.9 more which means E works 0.9hrs less and shares 0.4 less with C having 0.5 less which gives B an extra 0.4 instead of 0.9
This equates to B: 5.9 , C: 3.9 , E: 5.1
We can change to B: 6 , C: 3.94 , E: 5.4
= E+B = 11.4 = 11
= E+C = 8.99 = 9
= B+C = 9.94 = 9.9
Percentages of fixed net pay when B: 6 , C: 3.94 , E: 5.4 = 6+ 3.94+ 5.4 = 100
Time when 15.34 hrs = 100% if working same rate changes to 16.5hrs to account for the hours given 8am-1.30pm 8am-1.30+ 9am-1.30+ = minimum 1hr more = 2pm
Cal worked 8 am till 1.30 pm = 5.5hrs = 1.66hr extra
Ben worked 8am till 2pm = 6 hrs = 0 hr extra together worked 11.5hrs
Elsa worked 9am till 2pm = 5 hrs = -0.4hr less
11.5+ 5 = 16.5 This equals 16.5hrs = 100%
Ben earned the most as 6 of 16.5 as a percentage = (6*100):16.5 =36.36%
Cal earned the average as 5.5 of 16.5 as a percentage = (5.5*100):16.5 =33.33%
We check with Elsa and she earned the least as (5*100):16.5 =30.31% is the same as 100-69.67%
