Question 41127
{{{-15 < -5(s - 5)<= 30}}}
Multiply each term by -1 and reverse the inequality signs
{{{15 > 5(s - 5) >= -30}}}
divide through by 5
{{{3 > s - 5 >= -6}}}
{{{8 > s >= -1}}} answer
check some values. Let s = 7
{{{-15 < -5(s - 5) <= 30}}}
{{{-15 < -5(7 - 5) <= 30}}}
{{{-15 < -10 <= 30}}} TRUE
Let s = -1
{{{-15 < -5(-1 - 5) <= 30}}}
{{{-15 < 30 <= 30}}} TRUE
