Question

Which number is a solution of the inequality? 5(2q – 8) ≥ 7 A. 6 B. –2 C. −12 D. 92

Answer 1

`5(2q-8)\geq7\\10q-40\geq7\\10q\geq47\\q\geq4.7`

so the solution is not really a single number but a range, depending on how q is defined. I am assuming q is defined in domain of Real numbers, and then the solution to the inequality will be "all real numbers larger or equal to 4.7"
