r≥128
Step-by-step explanation:
To solve the inequality, we have to get r by itself. Perform the opposite of what is being done to the equation. Keep in mind, everything done to one side, has to be done to the other.
![\frac{r}{16}\geq 8](/tpl/images/1679/4759/f9163.png)
r is being divided by 16. The opposite of division is multiplication, so multiply both sides by 16.
![16*\frac{r}{16}\geq 8*16](/tpl/images/1679/4759/91d06.png)
![r\geq 8*16](/tpl/images/1679/4759/4e7e1.png)
![r\geq 128](/tpl/images/1679/4759/03efb.png)
Therefore, the answer is r≥128, or the last choice.
