Answer:
x
Step-by-step explanation:
Add 7 to other side making equation 16x
-71+7
16x-64
16 goes into -64 -4 times.
Answer would give you x-4
To check, you could substitute -4 into the inequality
16(-4)-7-71
-71-71 check
16(-10)-7-71
-167-71 check
Every 30 minutes. (this was using the LCM method)
I hope this helps, and have a good night! :D

8(x+5)
Distribute
8*x +8*5
8x+40
Answer:
a. 20x > 10x + 80
b. •20x > 10x + 80
• Subtract 10x from both sides: 20x -10x > 10x + 80 - 10x
• Simplify: 10x > 80
• Divide both sides by 10: 10x/10 > 80/10
• Simplify: x > 8
Step-by-step explanation:
10x + 80 = number of seashells Pilar has.
20x = number of seashells Marisol has.
answer for a: 20x > 10x + 80
answer for b: 20x > 10x + 80
• Subtract 10x from both sides: 20x -10x > 10x + 80 - 10x
• Simplify: 10x > 80
• Divide both sides by 10: 10x/10 > 80/10
• Simplify: x > 8
