You can put this solution on YOUR website! An oil tank was 1/10 full then 280 gallons was delivered which made it 8/10 full. If x= the capacity of the oil tank, what equation can be used to find the capacity of the tank?
.
Let x = capacity of the oil tank
.
From:"An oil tank was 1/10 full then 280 gallons was delivered which made it 8/10 full." we get:
(1/10)x + 280 = (8/10)x
.
Solving for x:
(1/10)x + 280 = (8/10)x
multiplying both sides by 10:
x + 2800 = 8x
2800 = 7x
400 gallons = x
