PLEASE HELP Jeannine runs for 45 minutes every day for exercise. It takes her 8 minutes to run a mile, and she spends 5 minutes

stretching halfway through the run. If x represents the number of miles she runs, then 8x + 5 ≤ 45 represents the time she runs each day. What is the fewest number of miles Jeannine must run to complete her daily exercise?

First, subtract 5 from each side to equal:
8x ≤ 40
Now, divide each side by 8:
x ≤ 5 miles

Hope this helps!! :)
