Help, please? Change this phrase into a math equation. Nine more than twice a number n is 12. A. 9 - 2n = 12 B. (9 + 2)n = 12 C. (2/9)n=12 D. 2n + 9 = 12 I think it's either B or D.

You think right my friend. Look at the sentence again. You have twice a number, n, AND that product also has nine MORE.
