Which represents the solution set of 5 (x + 5) less-than 85 x less-than 12 x greater-than 12 x less-than 16 x greater-than 16

For this case we must find the solution of the following inequality:

We apply distributive property on the left side of inequality:

We subtract 25 from both sides of the inequality:

We divide between 5 on both sides of the inequality:

Thus, the solution is given by all values of x less than 12.

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
