We have to represent the phrase "twice the difference of a number and five" as variable expression.

A variable expression is a mathematical phrase that can contain ordinary numbers, variables (like x or y) with operations as addition, subtraction ,multiplication and division.

Let the number be 'x'.

Twice of a number = [tex]2 \times x = 2x[/tex]

The difference of '2x' and 5 = 2x - 5

Therefore, the variable expression representing the given phrase is "2x-5".
