Answer:
she added 7/12
hope it helps
Step-by-step explanation:
so 4/12 is 1/3 she reached 2/3 so she would be at 8/12. take away 1/12 cause she started with that so you get 7/12.

Move values to create a proportion that can be used to solve the problem.
i need step by step explanation for this!!
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.

i need the answer rn please no pressure
Answer:
See explanation
Step-by-step explanation:
You can see that each time the number is doubling cuz 0.25 times 2 is 0.5 and so on. So now we know that the numbers are increasing so the next 3 terms have to be 2,4, and 8

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")

Why is the ratio of two integers always a rational number?
Answer: Rational numbers are numbers that can be written as a ratio of two integers.
Step-by-step explanation:
Answer: By definition, that is why they are called rational. They usually look like fractions: an integer in the numerator and an integer in the denominator.
Step-by-step explanation: Decimal equivalents of fractions are also rational numbers. Some decimal equivalents are not actually rational because the values they represent are not rational. For example: Pi. and the square roots of most integers 2,3,5,6...

Answer:
y = 6x
Step-by-step explanation:
So for this we simply find a x and y coordinate (ex. (10, 60))
Since we see that the y coordinate is 6 times of the x coordinate, we know that the equation for this proportional relationship is y = 6x.

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.
HOPE THIS HELPED :)

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.
In 2003, the population of an African country was about 7.8 million people, which is 1 million more than 4 times the population in 1950.
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

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

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

● 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
