Answer:
10
Step-by-step explanation:
We know that the average of two numbers are the numbers divided by 2, right?
So the equation would be this
X + Y/2 = 12
x + y = 24, since 24 divided by 2 is 12.
You should add x (6) to 24 and wind up with 30
Now to get the average between those 3, divide by 30 by 3
you should get 10

Answer:
10
Step-by-step explanation:
If the average of x and y is 12
(x+y)/2 =12
x+y = 2*12
x+y =24
We want the average of x+y+z
(x+y+z)/3 =
We know x+y =24 and z =6
(24+6)/3
30/3
