Answer:

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

Which equation, when solved, results in a different value of x than the other three?
kicyunya [14]
I would have to say -7(1/8)x-4/3=20.


The first and the second one both result in
-23 5/7

The last one results in -24 8/21

but the third one is -22 3/8.

So your answer is either the third of the last one. I assumed the third because, it is lower than all others and the first two are closer to 24 than they are to 22. It’s your choice on how to judge it.

1. Marcus can type 40 words in half a minute. Rhys can type 100 words in one and a half minutes. Which student can type at a gre
Bingel [31]
If Marcus can type 40 words in half a minute, then 40 times 2 equals 80. 80 words a minute for Marcus. If Rhys can type 100 words in 1 1/2 minute, 100/ 1.5 = 66.66 and 80>66.66 so Marcus can type a greater rate of words per minute.
