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

10
