1. 6 1/2 or 6.5 or 13/2
2. 10
3. -6
4. −8x9+3x8−2x
5. −32x3+120
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
