use cross products
(3r+6) *2 = 9*(2r-4)
6r+12 = 18r-36 distribute
12 = 12 r -36 subtract 6r from each side
48 = 12r add 36 to each side
4=r divide by 12
Answer:
The answer is 7

Power = 175 hp
The correct formula to calculate the power is:
Power = weight * (speed / 234) ³
Where the weight is that of the vehicle plus the driver's
Therefore the calculation is as follows:
Power = (2200 + 180) * (98/234) ³
Power = 174.8266 hp
Rounding ...
Power = 175 hp
