3. Six less than twice a number is 17. Which equation could be used to determine the

number, n?

A. 6-2n = 17

B. 2n-6 = 17

C. 6 - 7 n = 2n

D. 2n + 6 = 7

Answer & Step-by-step explanation:

n represents our number. So, twice a number would be 2n because twice means multiply by two.

When the problem says 6 less, then it means 6 less than 2n. So, it would look like 2n-6.

FInally, the problem says that all of this equals 17 so 17 would be the result.

So, you answer is 2n-6 = 17. This is answer choice B.
