$94.24

Step-by-step explanation:

Given :

Diameter of circular slab = 18feet

Thickness of slab = 3 inches ; inches to ft = 3 /12 = 0.25 feets

Volume of slab = πd²t/4 = (π*18²*0.25) / 4 = 63.6 ft³

1 cubic yard = 27 feet

Volume in yard = 63.6 / 27 = 2.356 yd³

Concrete = $40 per yd³

Cost = $40 * 2.356 = $94.24

Okay...but it is not an inequality, it is just a system of equations

y = x - 12so sub in x - 12 for y in the other equation

x + y = 8
x + x - 12 = 8
2x - 12 = 8
2x = 8 + 12
2x = 20
x = 20/2
x = 10

y = x - 12
y = 10 - 12
y = -2

solution is (10,-2)
