Answer: C. r+6>45

Step-by-step explanation:

Since, Dr. Cheeks tries to run at least 45 rotations on her hamster wheel each week.

If she runs r rotations then, for the value of r, [tex]45\leq r[/tex]

Since, If she has already 6 rotations

Therefore total rotation she has = r+6

Thus, if [tex]45\leq r[/tex] ⇒[tex]45<x+6[/tex]

So, Option C is the correct option.

The inequality of option C r+6 > 45 shows the rotations, r, she would have to run to meet her weekly goal.

Inequality is defined as the relation which makes a non-equal comparison between two given functions.

Dr. Cheeks tries to run at least 45 rotations on her hamster wheel each week.

She has already 6 rotations but if she runs r rotations then, for the value of r, 45 ≤ r

The total rotation she has = r+6

Thus, 45 ≤ r

= 45 < r + 6

or r+6 > 45

So, Option C is the correct option.
