She jogs 3000 feet in 5 minutes, divide 3000 by 5 to find out how many feet she can jog in 1 minute:
3000 / 5 = 600 feet in 1 minute.
Now multiply 600 feet by 8 minutes:
600 x 8 = 4,800 total feet.
Given:
five times a number = 5x
decreased by 8 = 5x - 8
is at most 10 = maximum is 10 so less than or equal to 10
more than twice the number = greater than 2x.
2x < 5x - 8 <u><</u> 10
5x - 8 <u><</u> 10
5x - 8 > 2x

5x - 8 <u><</u> 10 if x = 3.60 then 2x < 5x-8 <u>< </u>10
+ 8 +8 2(3.6) < 5(3.6) - 8 <u><</u> 10
5x <u><</u> 18 7.2 < 10 <u><</u> 10
÷5 ÷5

5x - 8 > 2x x > 2.67; if x = 3
