Because 5(1.50) is equal to 7.50 and they subtract it from both sides so that they can be left with the stapler and how much was spent on the stapler. You can replace d+7.50-7.50 with d because 7.50-7.50 is equal to zero
Answer:
12 feets
Step-by-step explanation:
Let the area of the pool be Length×width
There will be 2lengths and 2widths as well so the perimeter of the pool will be the addition of all the sides of the pool i.e 2L + 2W = 96... (1)
And since the length of the pool is 3 times its width, we have
L = 3W... (2)
Substituting equation 2 into 1 to get the width 'W'
2(3W) + 2W = 96
6W + 2W = 96
8W = 96
W = 96/8
W = 12feets
The width of the pool is 12feets
