Answer:
Step-by-step explanation:
Given
Rate of Long family's sprinkler is 25 L/hr
rate of Harris family's sprinkler is 35 L/hr
Total time for which sprinkler is used =55 hr
Let long family run their sprinkler for x hr
therefore Harris family time=55-x
Total volume collected=1625 L
thus

25x+1925-35x=1625
1925-1625=10x
300=10x
x=30 hr
long family used for 30 hr and Harris family used for 20 hr
-3x-42>3
-3x>45
x<-15
I chose x<-15 because through the process of elimination, if it was an equality, x=-15. Since it is an inequality, when dividing both sides by a negative, the sign switches.
