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.

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

● Answer:
b) 24 cm
● Step-by-step explanation:
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

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.

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

Hello! :)
Answer:
[tex]\huge\boxed{751}[/tex]
Let the smallest digit, or the units' digit, be equal to x:
Tens' digit is four more, therefore:
x + 4 represents the tens' digit.
Hundreds' digit is 2 more than the tens' digit, so:
2 + (x + 4), or x + 6 represents the hundred's digit.
These all sum up to 13, so write an expression to represent this:
x + (x + 4) + (x + 6) = 13
Combine like terms:
3x + 10 = 13
Subtract 10 from both sides:
3x = 3
Divide both sides by 3:
x = 1
Find the digits using the rules listed above:
Hundreds' digit: (1) + 6 = 7
Tenths' digit: (1) + 4 = 5
Units' digit: 1 = 1
Therefore, the number is:
751.

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

6^9 / 6^3 Please simplify I need help
Answer:
6^6
Step-by-step explanation:
The applicable rule of exponents is ...
(a^b)/(a^c) = a^(b-c)
In this problem, that means ...
(6^9)/(6^3) = 6^(9-3) = 6^6
__
It can help to remember that an exponent signifies repeated multiplication. Written out without exponents, the problem is ...
[tex]\dfrac{6\cdot6\cdot6\cdot6\cdot6\cdot6\cdot6\cdot6\cdot6}{6\cdot6\cdot6}=6\cdot6\cdot6\cdot6\cdot6\cdot6=6^6[/tex]
Note that the 3 instances of 6 in the denominator cancel 3 from the numerator. Clearly, the effect is the same as subtracting exponents.
Answer: 6^6
Step-by-step explanation: Formula - (a^b)/(a^c) = a^(b-c)
keeping the formula in mind;
= 6^9/6^3= 6^(9-3)
= 6^6
