A rectangle has 4 sides: 2 widths and 2 lengths. We know the two lengths and the two widths are the same (otherwise it wouldn't be a rectangle!).
If the width is 5, then we add another 5 for second width. That's 10 total.
32 - 10 = 22. This is the total of both of the lengths. As we mentioned before, we know each length is the same, so we can cut this in half.
Each length is 11.
11 + 11 + 5 + 5 = 32.
Each length is 11. Each width is 5.
Since the amount of money earned is based of of the amount of pies he sells...
y = 14x
Hope this helps!
Step-by-step explanation:
you can follow the same procedure for others
60 plain pizzas last week
42 fewer pizzas this week
Number of pizzas sold this week = 60 - 42 = 18
60 ------------------------- 100
18 ------------------------ x
x = (18 x 100)/60
x = 1800/60
x = 30%
The percent change will be 100 - 30 = 70%
