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 = 20Since x = 5:(5 + y) / 2 = 20Now, we can solve for "y":5 + y = 2 * 20 5 + y = 40Subtract 5 from both sides:y = 40 - 5 y = 35So, 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.
