If m - 4 is 7 more than n, then m + 9 is how much more than n + 2?

5
11
13
15
18

Translate each statement to math. Remember:
more means +
is means =
how much tells us to use a variable

Question:
(m + 9) = x + (n + 2) -> LOOKING FOR X
x = (m + 9) - (n + 2)
[spoiler]x = m - n + 7[/spoiler]
So we need to know [spoiler](m - n)[/spoiler] to get x

Given:
(m - 4) = 7 + n
m = 11 + n
[spoiler]m - n = 11[/spoiler]

So, x = m - n + 7
[spoiler]x = 11 + 7 = 18[/spoiler]

I think Anurag has made a slight typo, everything he says in both posts is correct but the answer should be E

Thanks a ton!!!!!!!:)

if (m-4) is 7 more than n, m is 11 more than n.
Therefore m+ 9 is 20 more than n and 18 more than n+2
ans E
