The Ross family and the Morgan family each used their sprinklers last summer. The water output rate for the Ross family's sprinkler was 20 L per hour. The water output rate for the Morgan's family sprinkler was 40 L per hour. The families used their sprinklers for a combined total of 60 hours, resulting in a goal water output of 1700 L. How long was each sprinkler used?

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24
