Answer:
x > 31
Step-by-step explanation:
Given
- 5x + 5 > 160 - 10x ( add 10x to both sides )
5x + 5 > 160 ( subtract 5 from both sides )
5x > 155 ( divide both sides by 5 )
x > 31
A. -3(-1) + 7 = 4
3 + 7 = 4
11 = 4 (wrong)
B. 4x - 8 = 12
4(-1) - 8 = 12
-4 - 8 = 12
-12 = 12 (wrong)
C. -2x + 3 = 1
-2(-1) + 3 = 1
2 + 3 = 1
5 = 1 (wrong)
D. 8x + 5 = -3
8(-1) + 5 = -3
-8 + 5 = -3
-3 = -3 (correct!)
So, in conclusion, D is the correct answer.
