Question

How do you write an algebraic expression for the phrase "a number added to 10"?

Answer 1

10+x

Explanation:

X represents the unknown number that is being added to 10.
The unknown number doesn't have to be represented by x, it can be any letter in the alphabet.

Answer 2

The algebraic expression is `x+10`.

Explanation:

To represent a number, choose a letter (I chose `x`). The phrase "added to" means plus. Now, you can rewrite the expression:

`stackrel(x) overbrace("A number") " " stackrel(+) overbrace("added to") " " stackrel(10) overbrace("10") "."`

The final expression is `x+10`.
