14 elliptical machines
Step-by-step explanation:
t = # of treadmills

e + 10 + e = 38
2e = 28
e = 14
The average number of goals per game Peter scores, rounded to one decimal place is 1.6
<u><em>Explanation</em></u>
In first two games Peter scored 2 goals each. So, total score in two games = (2×2)= 4
In one game he scored 0 goal and in next two games he scored 3 goals each, so the total is (3×2)= 6
In the last four games he scored 1 goal in each, so the total is (1×4)= 4
So, the total score in all
games 
Thus, the average number of goals 
So, the average number of goals per game Peter scores, rounded to one decimal place is 1.6
