Answer:
a. 3/5
b. 6 hours
c. 9 hours
Step-by-step explanation:
Given: Dave can clean pools at a constant rate of 3/5 pools/hour.
this means he cleans 3 pools in 5 hours
a.the ratio of number of pools to the number of hours= 3/5
b. since, we can clean 3 pools in 5 hours
this means he can clean 1 pool in 3/5 hours
so, he can clean 10 pools in 10×3/5 hours = 2 hours.
c. so, for 15 pools it will take 15×3/5 = 9 hours

Y= -1/4x - 1/4
Hoped this helps
A means x
b means y
