8x+6+4= 3x- 2x- 4 is the correct step
- Let r represent Rick’s height.
- Therefore, the quotient of Rick’s height and 4
- Fred is 5 inches shorter than the quotient of Rick’s height and 4.
- Therefore, an expression that represents Fred’s height is

Answer:
x = 12.75
∠C = 51.75°
Step-by-step explanation:
The two marked angles are complementary, so ...
(5x -12) +(3x) = 90
8x = 102
x = 102/8
x = 12.75
__
C = (5x -12)° = (5(12.75) -12)°
∠C = 51.75°
__
<em>Check</em>
E = 3x = 38.25, then C+E = 51.75 +38.25 = 90 . . . . as it should
