hope this helped :)

Explanation:

im not sure what you mean by image questions, but ill help you with part 2!

1. lets do this equation using PEMDAS

-(-1/2) - (3)(-2)

(1/2) - (-6)

1/2 + 6=

6 1/2 or 6.5 or 13/2

2. -20 ÷ (4 − (10 − 8))

-20 ÷(4-(2)

-20 ÷(2)

-10

3.

-(7−9)−2(−5−(−9))

−(−2)−2(−5−(−9))

2−2(−5−(−9))

2−(2)(4)

2−8

−6

4. 3x8−2x7−8x9

i think all you have to do here is rearrange the order

−8x9+3x8−2x

5. 4[30-(10-2)x3]

(4)(30+−8x3)

(4)(30)+(4)(−8x3)

120−32x3

−32x3+120
