A. x+70<63

B. x-70<63

C. x+70≤63

D. x+70≤-63

E. x-70≤63

Answer: C

Explanation:

From the given condition, we can say that -133≤x≤-7

Now, we need to see which option will give you the same range by expanding every option.

Eliminate options A and B as we need ≤.

Check Option C.

x+70≤63

-63≤x+70≤63

Subtract 70 from every part, we get -133≤x≤-7

Hence, the answer is C.
