Question

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

Answer Choices:
A. {r | r < 11}
B. {r | r > 11}
C. {r | r < 12}
D. {r | r > 12}

Answer 1

If I may help?

Answer 2

and What did you pick?

Answer 3

I don't quite understand how to do it, so I was needing the steps to solve. I wasn't necessarily looking for just an answer.

Answer 4

Ok
Step by step.

Can you solve this inequality for r?

Answer 5

\[\Large 5r+8<63\]
\[\Large 5r+8-8<63-8\]
\[\Large 5r<\]
\[\Large \frac{ 5 }{ 5 } r<\frac{ 55 }{ 5 }\]
\[\huge \color{blue}{\text{r<11}}\]

Answer 7

Now you can write the solution of r in set-builder notation:
\[\huge \color{orange}{\text{Solution = {r | r < 11}}}\]

So it'd better to choose: A
