Answer:
I dont know what you are supposed to answer with but I'll try to help you out. I take it that you have to find the letter ex. the letter d in 1/2d = 7. What you have to do is to get the d by itself and in order to do that you must move the 1/2 over to the 7. So what you would have to do is take the fraction that has the letter on it and move it to the whole number side or the side without the letter but without moving the d.The d stays on one side while the other numbers are on the other side. When you move the 1/2 over it should look like this sort of due to the limitations of only being able to use text: d = 7 ÷ 1/2. Now after that you have to divide 7 by 1/2 or .5 for question 13 in this instance. Your answer for 13 should be this: d=4.5Makesuretoshowallyourworkjustincase.
13. d = 4.5
14. 18 = f
15.-9=s
16.-24 = r
17. 0.125 = y
18. -3 = v

1/14 minute
1/7in=1/14min
14/7in=min
2in=min
The rate is 2 inches per minute
The unit rate for the given problem, 1/7 inch per 1/14 minute, is calculated by dividing the inches by the minutes. This simplifies to 2 inches per minute.
In mathematics, a unit rate is a rate in which the second number (or denominator) is one. When you are asked to write the rate 1/7 inch per 1/14 minute as a unit rate, you are being asked to find a rate that tells you how much of each quantity occurs for each single unit of the other quantity, in this case for 1 minute. To calculate this unit rate, divide the quantity in inches by the quantity in minutes.
In this problem, you can find the required unit rate by dividing (1/7) by (1/14), which simplifies to (1/7) * (14/1) = 2 inches. So, the unit rate for this problem is 2 inches per minute.

50 cents
➁ 4.25 ÷ 8 = 0.53125
53 cents (rounded)
➂ 7.49 ÷ 17 = 0.440588235
44 cents (rounded)
➃ 2.05 ÷ 3 = 0.683333333
68 cents (rounded)
Answer:
Part A:

➁ Pop Kornz: 53 cents per ounce of popcorn
➂ Pop-arazzi: 44 cents per ounce of popcorn
➃ Kernels Popcorn: 68 cents per ounce of popcorn
Part B: The unit rates found in Part A represent the cost per each ounce of popcorn
Part C: The best package to buy is Pop-arazzi because it cost less per-pound of popcorn. (44 cents per ounce of popcorn)
44¢ < 50¢ < 53¢ < 68¢
➂ < ➀ < ➁ < ➃
Pop-arazzi < Pop-A-Lot < Pop Kornz < Kernels Popcorn
