Question

The average of 3,3,16,19, and y is 10. what is y+6?

Answer 1

y=9

9+6=15

y+6=15

Explanation:

3+3+16+19+y=41+y

41+y/5=10

multiply both sides by 5

205+y/5=50

41+y=50

Rearrange the equation so y is isolated.

y= 50-41

y=9

Check:

3+3+16+19+9=50

50/5=10

y=9

y+6=?

9+6=15

Hope this helps :)
