In segment ac, the midpoint is b. if segments ac = 5x-9 and ab= 2x what is the measure of ac? can you show their work on paper or something so i can understand more?

The answer to your question is: AC = 36

Step-by-step explanation:

Data

Segment AC with midpoint = B

AC = 5x - 9

AB = 2x

AC = ?

Process

           total length = AC  but B is the midpoint so AB + AB = CA

                                                                                  2AB = CA

                Substitution        2(2x) = 5x - 9

                                             4x = 5x - 9

Solve for x                           4x - 5x = -9

                                             -1x = -9

                                              x = -9/-1

                                             x = 9

Finally,            AC = 5x - 9

                             = 5(9) - 9

                             = 45 - 9

                             = 36

what is the graph

step-by-step explanation:

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.
