Answer:
3, 4 and 5
Step-by-step explanation:
The total number of marbles Janae, Jerome and Gwen have is m + m + 4(m + 2).
m + m + 4(m + 2)
= 2m + 4m + 8
= 6m + 8
The problem says that the total number of marbles Janae, Jerome and Gwen have is less than the number of marbles John has, so that means 6m + 8 is less than 8m + 4
6m + 8 < 8m + 4.
(6m + 8) - 4 < (8m + 4) - 4
6m + 4 < 8m
4 < 8m - 6m
4 < 2m
1 and 2 aren't valid so the answer is 3, 4 and 5.
