Question

Represent the following sentence as an algebraic expression, where "a number" is the letter x. You do not need to simplify.Twice the difference of a number and 5.

Answer 1

`2(x-5)`

Step-by-step explanation

We want to represent the sentence below as an algebraic expression:

Twice the difference of a number and 5.

The number is going to be represented by x.

To do this, we to write the expression in the same flow as the sentence, in other words, write it in the manner with which the sentence is given:

=> Twice means two times:

`2()`

=> The difference between a number and 5 is:

`x-5`

Therefore, twice the difference of a number and 5 will be:

`2(x-5)`

That is the answer.
