skelet666 [1.2K]

Answer:

58

add up all the numbers:

13 + 13 + 14 + 18 + 22 = 80

the mean is 23.

so you need to back track:

23 * 6 = 138

138 - 80 = 58

How many home runs did each player hit the season
olya-2409 [2.1K]
Let Peter's hit be x and Alice's runs be y.
x = 2(y - 6) . . . (1)
x + y = 18 . . . (2)

Putting (1) into (2) gives,
2y - 12 + y = 18
3y = 18 + 12 = 30
y = 30/3 = 10
x = 2(10 - 6) = 2(4) = 8

Therefore, Peter hit 8 home runs and Alice hit 10 home runs.
