Answer:
x = 34
Step-by-step explanation:
The sum of the three angles is 180 since they make a straight line
x+12 + 100 +x = 180
Combine like terms
2x+112=180
Subtract 112 from each side
2x+112-112= 180-112
2x = 68
Divide by 2
2x/2 =68/2
x = 34
Answer:
Simplifying
x = 11
Step-by-step explanation:
Simplifying
6x + -27 = 39
Reorder the terms:
-27 + 6x = 39
Solving
-27 + 6x = 39
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '27' to each side of the equation.
-27 + 27 + 6x = 39 + 27
Combine like terms: -27 + 27 = 0
0 + 6x = 39 + 27
6x = 39 + 27
Combine like terms: 39 + 27 = 66
6x = 66
Divide each side by '6'.
x = 11
Simplifying
x = 11

Answer:
$130
Step-by-step explanation:
To find the tip you have to change the percent into a fraction first. Since percent is out of a 100, 25% is 25/100 or 1/4. Multiplying 1/4 by 520 you get 130, which is how much the coach will tip.
