Maggie's brother is four years younger than twice her age the sum of their ages is 11 how old is maggie?

Her brother is 11 so maggie is 2 times older minus four years. So 11= 2y-4
subtract four from both sides and then divide by 2 from both sides. I'll let you do your own homework but thats the equation and steps.

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 : )
