Question 209882
<font face="Garamond" size="+2">


If B is between A and C, then AB + BC = AC. The converse is also the same. If AB + BC = AC, then B is between A and C.


So, for your problem 31, presuming that the points are labeled in alphabetical order, you can say:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ (3x + 8) + (2x - 5) = 23]


Just solve for *[tex \Large x].


Solve the other problem the same way.
