What is an expression to represent the equation

Tatiana [17]

Answer:

8 + $\frac{x}{4}$

Step-by-step explanation:

I'm assuming you want an answer to the top section of the question.

We can start with 8.

When a problem asks for the sum, it's looking for addition, so we use the + sign.

8 +

The problem says "a number," so let's represent that with x. Basically, x just means a number we don't know.

8 + x

The "number" is divided by 4, so we'll just put x/4 as our second term.

8 + $\frac{x}{4}$
