Answer:
1. a = 87
2. b = 183
3. b = 41
4. c = 2,884
5. d = 570
Explanation:
To find the answers to any questions like these, all you need to do is use the inverse operation of the number.
For example, the inverse operation of - 160 ('minus 160' symbolizes negative 160) is + 160 (positive 160). So, add 160 to both sides of the problem. From there, you're left with b = 183.
