z divided by 3
The variable expression of "z plus 8" is represented as z + 8. In algebra, variables like z can take on different values, while constants like 8 remain the same. When you see "z + 8" in an equation or expression, it means that the variable z is being added to the constant 8.
(x + y + z) / 3 = 8 x + y + z = 24 if x=10 and y=10 10 + 10 + z = 24 20 + z = 24 z = 4■
|z - 8| or whichever of (z - 8) and (8 - z) that is non-negative.
Average of the three is v so their sum is 3v. One is z, another y so the third is 3v - z - y
