Answer:
I'm pretty sure it's 4 decimal places but that's not one of your answers so I don't know.
Step-by-step explanation:
16/9 because (3/4)^-2 simplified is 16/9
June=1,225
April=1,225
May=1,225
All June April and May is 3,675 haircuts
Simplify -5x + 12 - 7x to -12x + 12
-12x + 12 = -3(5x + 8)
Expand
-12x + 12 = -15x - 24
Add 15x to both sides
-12x + 12 + 15x = -24
Simplify 12x + 12 + 15x to 3x + 12
3x + 12 = -24
Subtract 12 from both sides
3x = -24 - 12
Simplify -24 - 12 to -36
3x = -36
Divide both sides by 3
x = -36/3
Simplify 36/3 to 12
<u>x = -12</u>
