Question

What is half the sum of x and y decreased by one-third y as a algebraic expression

Answer 1

Answer:

$\frac{1}{2}(x+y) - \frac{1}{3}y$

Step-by-step explanation:

We can translate these words into an expression by just reading them and interpreting them.

Half the sum of x and y.

We know that it's going to include $(x+y)$, and if we're taking half of that, we multiply that by $\frac{1}{2}$, so $\frac{1}{2}(x+y)$

We also know that one third of y will be multiplying y by $\frac{1}{3}$, so $\frac{1}{3}y$.

Since we are decreasing $\frac{1}{2}(x+y)$ by  $\frac{1}{3}y$, there's a minus sign between the terms.

So, $\frac{1}{2}(x+y) - \frac{1}{3}y$.

Hope this helped!
