If there was a graphical representation, I would be happy to assist you.
The average would be the total amount divided by the 2 groups, so the answer would be 37.5 years old.
The anawer to your question is 3/6, and simplified as 1/2.
Step-by-step explanation:
Given that,
BC = 8
Ac = 15
We can find AB using the pythagoas theorem.

We know that,
, B is base and H is Hypotenuse

Hence, this is the required solution.
2p+6a=$14
3p+9a=$21
3p+9a=21
Subtract 9a
3p=21-9a
divide all by 3
p=7-3a
plug it into start equations
2p+6a=14
2(7-3a)+6a=14
14-6a....+6a=14
this zeroes out...
