Danielle ran a total of 15 miles over the course of 5 track practices. how many track practices would it take for danielle to run 18 miles? assume the relationship is directly proportional.

Respuesta :

You would set up the equation like this:(15/5) = (18/x). Then just solve.
3= (18/x)
3x=18
X=6
So 6 track practices.
