Answer:
C: x≥12
D: x<-15
E: x<7.5 or 15/2
F: x<-8
G: x≥-2.7 or -8/3
H: x≥-6
Step-by-step explanation:
I trust you know how to graph it
45/5 = 9minutes/wall = 1wall/9minute/4 people = (1/36) per minute per person
(1/36)*6 = 1/6 wall per minute per 6 people * 24 = 4 walls in 24 minutes
24 Minutes total
Take 20 laps divide by 8 then take the number times 9 laps
20 percent
If you cross multiply 30 w/ 100 and then divide it by 150 you will get 20.
