You need to drain your swimming pool. The pool has 1500 gallons of water. It drains at a rate of 150 gallons per hour. a.) Write an equation to model the situation.
b.) how many gallons will be left in the pool after it has drained for 6 hours?
c.) how many hours has the pool drained if it has 150 gallons left.

a.) i dont know how to write equations

b.) 600 gallons

d.) 9 hours

Step-by-step explanation:

Step-by-step explanation:

a. 150 x 10h (h = hours) = 1500

b. 150 x 6h = 900. 900 gallons have drained from the pool after 6 hours.

c. 9 hours. the pool has drained for 9 hours if there is 150 gallons left. (150 x 9 = 1350. 1500 - 1350 = 150.)

you can't solve x because it is 2 linear equation and you only have one equation
