6w=w+x+y
(w+x+y)/3 = 2w

Arithmetic mean =2w

To find: w+x+y/3............... eq.1
Given: 5w= x+y...................eq.2

Putting the value from eq. 2 in eq. 1
Average= w+5w/3= 6w/3= 2w

Why do we add w? I tried plugging in a number like 3 for w and 10 and 5 for x and then tried adding all three and dividing by 3.

A. 2w
B. 3w
C. w + 2
D. 1/3*w
E. 1/2*w


We need to determine the average of w, x, and y, or the value of (w + x + y)/3. Since 5w = x + y, we can say:

(w + 5w)/3 = 6w/3 = 2w

Answer: A
