The question lacks information.
Let's start by finding the value of "y" using the information that the average of x and y is 20 and that x is equal to 5:
Average of x and y = (x + y) / 2 = 20
Since x = 5:
(5 + y) / 2 = 20
Now, we can solve for "y":
5 + y = 2 * 20 5 + y = 40
Subtract 5 from both sides:
y = 40 - 5 y = 35
So, we have found that y = 35.
Now, to find the average of x, y, and z, we need to know the value of "z." If "z" is not given, we cannot determine the average.
