Brad bought a used bike for $8 more than half of its original price. Brad paid $40 for the bike. What was the original price?
Viefleur [7K]

\huge\boxed{\$64}

40=8+\frac{y}{2}

Subtract 8 from both sides.

32=\frac{y}{2}

Multiply both sides by 2.

\boxed{64}=y

The supplement of an angle is 3 times the complement of an angle.
-Dominant- [34]
Let’s says that x is the measure of the angle. X and it’s supplement are equal to 180. X and it’s complement are equal to 90. The supplement is s and the complement is c. S is times c which is the same as 3c.

3c + x = 180

C+x = 90
X = 90 - c

3c + 90 - c = 180
2c = 90
C = 45

The complement of. 45 degree angle is 45 degrees.

The angle is 45 degrees.
