is the average of 27 - x, x - 8, and 3x + 11 is y, what is the average of 2y and 2y/3?
Average
y=((27-x)+(x-8)+(3x+11))/3
The average of
2y and y/3 is
(2y+y/3)/2
=(7/6)y
=(7/6)*((27-x)+(x-8)+(3x+11))/3
Simplify.
y=((27-x)+(x-8)+(3x+11))/3
The average of
2y and y/3 is
(2y+y/3)/2
=(7/6)y
=(7/6)*((27-x)+(x-8)+(3x+11))/3
Simplify.
