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