Answer the question math

Lerok [7]

Answer:

$7y-10$

Step-by-step explanation:

$9y-\frac{1}{2}\left(4y+20\right)$

To simplify this expression, first use the distributive property to distribute $\frac{1}{2}$ .

$9y-\frac{1}{2}(4y)+-\frac{1}{2}(20)$

Simplify.

$9y+-2y+-10$

Combine like terms, $9y$ and $-2y$ .

$7y-10$

The simplification of $9y-\frac{1}{2}(4y+20)$ is $7y-10$ .

I hope this helps ^^

Good luck
