Answer:
hey bud i dont think you finished the question?
Step-by-step explanation:
A-action games
s-sports games
a+s=47
a=s+21
I replace the action games in the first equation
s+21+s=47
2s+21=47
2s=47 - 21
2s=26
s=26:2
s=13 number of sport games
a=13+21
a=34 number of action games
It would be (6)4a-3b Because six is the greatest common factor. You just have to divide the other numbers by six and then bam :)
If change from 313 to 533
a) median: It increased by 15
b) mean: It increased by 22
