Answer:
a> -3
Step-by-step explanation:
Step 1: Add 1 to both sides.
−9a−1+1<26+1
−9a<27
Step 2: Divide both sides by -9.
−9a
−9
<
27
−9
a>−3
2(4 + 2x) > = 5x + 5
Distribute the 2
8 + 4x > = 5x + 5
Subtract 5x from both sides
8 - x > = 5
Subtract 8 from both sides
- x > = -3
Divide both sides by -1
When dividing by a negative, change the inequality sign.
x < = 3
Answer:
Number of week they have same amount = 4 week
