Question

Half the sum of x and y decreased by one-third of y

Answer 1

The expression that represents half the sum of x and y decreased by one-third of y is ((x + y)/2) - (y/3).

Step-by-step explanation:

The question is asking for the expression that represents half the sum of x and y decreased by one-third of y. Let's break it down:

Half the sum of x and y can be written as (x + y)/2.

One-third of y can be written as y/3.

To find the expression that represents this, we subtract one-third of y from half the sum of x and y:

((x + y)/2) - (y/3)

This is the final expression that represents half the sum of x and y decreased by one-third of y.

Answer 2

Your question doesn't really make since but... 1/2(x+) - 1/3y.
