Hi! [:D
I don't know how to solve this problem. Could you help me out? I do not understand part "b".
4a. State the Segment Addition Postulate using the diagram. (Picture of a S.A.P. with points A,B and C in that order)
4b. If JE=x+3, JM=4x-7, and EM=11, find JE and JM.

SAP: if B is between A and C, then AB + BC = AC.
thus JE + EM = JM or x+3 + 11 = 4x-7

anonymous · Answer

So I solve the equation right?

oblivious · Answer

solve and then plug x into the equations for JM and JE

anonymous · Answer

Ok..doing it now...

anonymous · Answer

x+3+11=4x-7
x+14=4x-7
   +7       +7
x+21=4x
-x        -x
21     =3x
*Divide by 3 on both sides
x=7?

oblivious · Answer

yes, then plug bag into the original equations and you have both JE and JM

Oh! Ok. I get it now. Before, I thought x=3. I appreciate your help :D
