Answer:
B) 1.15x, adding 15% to the cost of haircut is same as to multiply cost by 1.15
Step-by-step explanation:
Given expression = x + 15% of x
x + (15/100) x = x + 0.15x
= (1+ 0.15) x = 1.15x
15% = 0.15 , added to x = 1.15x
Answer:
Simplifying
x + 8y = 15
Solving
x + 8y = 15
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-8y' to each side of the equation.
x + 8y + -8y = 15 + -8y
Combine like terms: 8y + -8y = 0
x + 0 = 15 + -8y
x = 15 + -8y
Simplifying
x = 15 + -8y
