Question

Write the solution to the inequality in set - builder notation:
5r + 8 < 63

Answer 1

First, the inequality needs to be solved. The first step is to subtract 8 from both sides of the inequality, leading to 5r < 55. Dividing 5 out from both sides, this will leave r < 11. Next, to form a set notation, the inequality is written in such form: r .
