Write the solution to the inequality in set-builder notation. 5r + 8 < 63
{r | r < 11}**
{r | r < 15}
{r | r < 71}
{r | r < 8}
thx i cheat my online school. these bafoons
yes.
{r | r < 11}
To find the solution to the inequality 5r + 8 < 63, we can follow these steps:
Step 1: Subtract 8 from both sides of the inequality:
5r + 8 - 8 < 63 - 8
5r < 55
Step 2: Divide both sides of the inequality by 5:
(5r)/5 < 55/5
r < 11
Therefore, the solution to the inequality is r < 11.
In set-builder notation, this solution can be represented as {r | r < 11}. So, your answer is correctly {r | r < 11}.
