Question

Which phrase BEST describes the expression below? 15.4 − 2 n

A.twice a number n minus fifteen and four-tenths

B.twice a number n subtracted from fifteen and four-tenths

C.a number n minus the product of fifteen and four-tenths and two

D.a number n times the difference between fifteen and four-tenths and two

Answer 1

B) is the answer, my reasoning is that A) is 2n - 15 and four tenths which is the wrong way around , C) is just nonsense and D) is n multiplied by 15 and four tenths take away 2 which is also wrong , as that would be n x 13 and four tenths , hope this helps :)

Answer 2

B is the answer hope this helps!
