Question

A tank currently holds 5 gallons of water. It is being filled at the rate of 1/4 gallon per minute . How long will it take for the tank to hold 9 gallons of water ?

Answer 1

1) 5b + 6 = 21
5b = 15
b = 3

2) 9 - 5 = 4 gallons left to be filled
.25x = 4
x = 16 minutes

3) x + 2/5 = 12
x = 12 - 2/5 = 60/5 - 2/5 = 58/5

4) 8 + a = 13
Subtract 8 from both sides (Both sides are equal, so performing the same operation on both sides is justified)
8 + a - 8 = 13 - 8
a = 5
