Answer 1

Hey!

Your answers are:

- 4 less than a number

- A number decreased by 4

Let k represent "a number". "k" is a variable, and variables are unknown.

-4 is subtracting 4. That means you're subtracting 4 from a number. -4 also means that the number is decreasing by 4. Therefore, those 2 are your answers.

I hope this helps!
