Last question: What equation represents three less than five times a number is twelve?

A. 3 - 5x = 12

B. 5x - 3 = 12

C. 5 (3 - x) = 12

D. 5 (x - 3) = 12

B, 5x - 3 = 12

Step-by-step explanation:

3 less means subtracting, it's going to be - 3.

It says 3 less than five times a number, meaning we don't know the number, so we can put it as x.

3 less means your subtracting from something, which would make it 5x - 3.

Finally, they state that it equals 12, making the equation 5x - 3 = 12.
