Answer:

#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 #-># this means that you are adding something, so you're going to use the #+# sign;

  • of a number #-># this means that you're dealing with a variable. The most common notation for a variable is #x#.

  • and 10 #-># 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#.
