Question

What is the expression for this word problem please help !!

A number added to 13 all divided by 2

Answer 1

Answer:

$\frac{13+x}{2}$

Step-by-step explanation:

"A number" is the part of the question you don't know, and therefore is the variable. Let's call it $x$ from now on.

So, when you add a number to 13 it means you are increasing 13 by that number, or $13+x$.

To divide it all by 2, simply put the above expression on a fraction with a denominator of 2:

$\frac{13+x}{2}$

And there is your answer.
