Question

read the description of a proportional relationship.
larry has outgrown the bike he rode when he was small. so, for his twelfth birthday, his parents surprise him with a five - speed blaze rider 2000! larry has never had a bike with multiple speeds before, and he is eager to learn how it works. he starts by testing the middle speed. there is a proportional relationship between the number of times larry pedals, x, and the number of times the wheels rotate, y.
the equation that models this relationship is y = 3x.
how many times does larry pedal when the wheels rotate 9 times? write your answer as a whole number or decimal.
______ times

Explanation:

Step1: Identify known values

We know the relationship is \( y = 3x \), and \( y = 9 \) (wheels rotate 9 times).

Step2: Solve for \( x \)

Substitute \( y = 9 \) into the equation \( y = 3x \), we get \( 9 = 3x \). Then divide both sides by 3: \( x=\frac{9}{3}=3 \).

Answer:

3
