In order to find out what deal is better:
- We have to find the unit rate for each deal
- Total amount of paper towels ÷ The price
So it would be....
- 18 ÷ 14 = 1.285714
- 12 ÷ 10 = 1.2
Short Answer:
The better deal is 10 rolls of paper towels for $12.
Long Answer:
I wanted to find out the price per roll of paper towel for each deal so I created a unit rate problem which is the numerator divided by the denominator. From there, I was able to get my answers, compare which one was less than the other, and select the best deal.

Answer:
8/15
Step-by-step explanation:
You plug in 2x in the equation for y. Since y =2x. 6x+7(2x)=8 6x+14x=8. 20x=8. X=8/20. X=2/5. Is your final answer
First pic: x=27
second pic: x=15
Answer:
length of rectangle = 32.25 cm
Width of rectangle = 10.75 cm
Step-by-step explanation:
Let the length of rectangle be x.
And width of rectangle be y.
According to the problem,
x = 3y {Since the length of a rectangle is equal to triple the width}
Also,
Perimeter of rectangle = 86
or 2 (x + y) = 86
Plug x =3y in the above equation
We get, 2(3y + y) = 86
2 * 4y = 86
4y = 43
y = 43/4 = 10.75
So, length of rectangle = 3 * 10.75 = 32.25cm
Width of rectangle = 10.75cm
