Isolate the x. Note the equal sign. What you do to one side, you do to the other.
Subtract 8 from both sides
x + 8 (-8) = -2 (-8)
x = -2 - 8
Combine
x = -10
-10 is your answer for x
hope this helps
Answer:
The answer is c
Step-by-step explanation:
negative degrees below zero is like two negative which equals a positive so in other wourd it would be the same as 10 degrees above zero

Percentage of tip that needs to be given for hair cut = 15%
Amount of tip is calculated without sales tax.
Amount taken for the hair cut = 20
Amount of sales tax taken = 4.75
Then
Amount of tip given = (15/100) * 20
= 300/100
= 3
So the total amount required for the hair cut = 20 + 4.75 + 3
= 27.75
So 25 is insufficient amount to cover the hair cut cost with tip and sales tax. The actual amount required to cover the total cost is 27.75<span />
First you got to subtract 100 from 50 than you have to divide 50 by 8 and then multiply by 3
