We know there is 57 members are in the math club and there is twice as many sixth grades than the seventh. To find out how many sixth graders are in the club, we do:
x = seventh graders
2x = sixth graders
2x + x = 3x
57=3x
57 ÷ 3 = 3x ÷3
19 = x
So there is 19 seventh graders and 19×2= 38 sixth graders
When finding the mean you should first add up all the numbers which are 12,2,8,6 and 57 which will give you a sum of 85 next you should divide your sum by how many numbers there are which is 5 and your answer should be 17
