A local gym has 2 types of cardio machines, treadmills and elliptical machines. There are 38 cardio machines in all. There are 10 more treadmills than there are elliptical machines. How many elliptical machines are at the gym? 9 elliptical machines 14 elliptical machines 24 elliptical machines 28 elliptical machines

Answer 1

Answer:

14 elliptical machines

Step-by-step explanation:

t = # of treadmills

e = # of elliptical machines

t + e = 38

t = e + 10

Substitute:

e + 10 + e = 38

2e = 28

e = 14
