Question

When she pedals 3 times, the wheels rotate 9 times. Write the equation for the relationship between x and y.

Answer 1

y=3x

Explanation:

The ratio here is 9/3=3 which means we can for the equation as

y=3x

where x is the number of pedals and y is the number of times the wheel has rotated

Answer 2

3x=9y

Explanation:

X are the pedals, and the pedals pedal 3 times, so its 3x

Y are the wheels and the wheels rotate 9 times so its 9x

Whenever the pedals pedal 3 times the wheels rotate 9 times making them equal to each other
