Anumber n is 13 less than a second number, and the second number is 10 more than a third number. if the third number is 54, what is n? a) 31 b) 41 c) 51 d) 57 e) 77

N = number
s = second number

n = s - 13
s = 54 + 10

s = 64

Plug in 64 for s

n = (64) - 13
n = 51

C) 51 is your answer

hope this helps

Skew lines(segments) are lines(segments) in 3 dimensions that do not intersect the given segment and are not parallel to it.  ae, bf, eg, and fh are your skew segments.  i hope that : )
