Question

Which number(s) below belong to the solution set of the inequality? Check all that apply. 9x >_117   A. 6 B. 8 C. 12 D. 14 E. 19 F. 13

Answer 1

Plug in each one of the candidate numbers where x is in the formula. So multiply the candidate number by 9 and evaluate whether or not it is greater than or equal to 117.
Example 9(6)= 54 54 is less than 117 and therefore is not a member of the solution set. Think of this as a true or false question.
