$x + 10$

#### Explanation:

Break down the information given to you to try and identify what the algebraic expression must looks like. You know that you're dealing with

• a sum $\to$ this means that you are adding something, so you're going to use the $+$ sign;

• of a number $\to$ this means that you're dealing with a variable. The most common notation for a variable is $x$.

• and 10 $\to$ this is simply an integer that must appear in the algebraic expression along the variable $x$.

So, put all this together to get

$x + 10$

You're adding an unknown number, $x$, to an integer, $10$.
