Question

What is the solution set for the given inequality if the
replacement set for r is {5, 6, 7, 8, 9, 10}?

2r ≤ 3r – 8

Answer 1

The sign that is in between of 2r and 3r means that 2r is less than or equal to 3r-8. You want to find a set of numbers that can actually replace the variable of r into both the coefficients of 2r and 3r.

Answer 2
