Answer:
Step-by-step explanation:
(fx+cd)/(x-f)=1/2
Cross multiplication,
2*(fx + cd) = 1 * (x-f)
2fx + 2cd = x - f
2fx - x = -2cd - f
x (2f - 1) = -2cd -f
x = (-2cd-f )/ (2f-1)
-5x + 5y = 40 -20x +20y =160 -5x + 5(8) = 40
4x + 3y = 24 20x +15y =120 -5x + 40 = 40
35y = 280 -5x =0
y = 8 x = 0

Answer: 375.9 sq ft</h3>
This is assuming there is no overlap.
===================================
Work Shown:
1 bag = 125.3 sq ft
3*(1 bag) = 3*(125.3 sq ft)
3 bags = 375.9 sq ft
We are going to have to divide...
We have to put 1 as a denominator for 3 because it's a whole.

Cross multiply.
