what is the answer to this problem

.

4/5 x 1 1/6 =

.

16% of 225 =

.

(-17) – (-22) =

.

8(6-5) + 10 =

.

4(-2)² + 8(-2) + 3(-2) + 6 =

.

(1/3)9³ =

.

-11(3/2)(.12(-12)) =

.

30 + (.0825 x 30) + (15% x 30) =

.

598% / 26% =

.

5(17)² / 10³ =

.

(-30(-7))-(210(-3)) =

.

If 2(x -1) = 14, then x =

.

If 5x + x² > 100, then x is not

.

If 5x – 17 = -x + 7, then x =
