Which algebraic expression represents “the difference of 54 and a number”?

54 - number=x

example 54 -1 =53

If it doesnt sorry :(

54-x

Explanation:

1. We define the variable which is x or n (whichever you choose)

2. We write the algebraic expression that models the following problem:

            the difference of 54 and a number.

3. We end up with our 54-n OR 54-x

(Variable doesn't matter but most people use x when they don't have a named variable)

Hope this helps!!
