Answer:
x = 6
One-fourth x + one-half = one-third x
Step-by-step explanation:
1/4 x + 1/2 = 1/3 x
1/4 x - 1/3 x = - 1/2
(3x - 4x)/12 = -1/2
-x/12 = -1/2
-x = -12/2
-x = -6
x = 6
X=5. this is true because if y=0 and y=15-3x, then 15-3x=0. if x is 5, it would be 15-3(5)=0.
42 gallons weigh 7(42) or 294 pounds
<span>each cubic foot weighs 52 pounds </span>
<span>so the number of cubic feet = 294/52 = 5.654 ft^3</span>
