Answer:
Billy used 28 mins 30 sec to mow the lawn and Bobby used 43 mins 30 sec to now the lawn both within 72 mins
Step-by-step explanation:
let x represent Billy
let x+15 represent Bobby
x + x + 15 = 72
2x = 72 - 15
2x = 57
2x/2 = 57/2
x = 28.5 minutes = 28 minutes 30 seconds
Bobby = x + 15
= 28.5 + 15
= 43.5 minutes= 43 minutes 30 seconds

Answer:
3.9 ≤ s ≤ 3.95
Step-by-step explanation:
The perimeter is 4 times the side length, so the inequality is essentially ...
P = 4s
15.6 ≤ 4s ≤ 15.8 . . . . . . substitute the expression that uses side length
3.90 ≤ s ≤ 3.95 . . . . . . divide by 4
