What does segment bisector mean?
 one year ago

valiyuh Group TitleBest ResponseYou've already chosen the best response.1
its a line that divides a segment in half?

mathstudent55 Group TitleBest ResponseYou've already chosen the best response.0
Right. In this case, I think M is simply a point, but it still cuts the segment JK into two congruent segments.

Since M is a bisector, what do you know about the length of JM and the length of KM?
 one year ago

valiyuh Group TitleBest ResponseYou've already chosen the best response.1
Well i know that since m is the bisector both sides are equal which mean that since JM is 1/8x MK is also 1/8x

Form the figure you see that JM + MK = JK, right?
 one year ago

mathstudent55 Group TitleBest ResponseYou've already chosen the best response.0
Great. Below JM, MK, and JK, can you write what each one is equal to? Copy my line below and write it below that line. JM + MK = JK

1/8x + 1/8x = 3/4x6 like this?
 one year ago

mathstudent55 Group TitleBest ResponseYou've already chosen the best response.0
Exactly. That is the equation you must solve now to find x.

\( \dfrac{1}{8}x + \dfrac{1}{8}x = \dfrac{3}{4}x  6\) Solve for x.

This is the part were im getting confused? Do i add both 1/8x to get 2/8x? or am i wrong?
 one year ago

mathstudent55 Group TitleBest ResponseYou've already chosen the best response.0
Yes, you are correct. \(\dfrac{2}{8}x = \dfrac{3}{4}x  6 \) The fraction on the left can be reduced.

alright so now i subtract the 3/4 to the other side so now its 2/8  3/4?
 one year ago

mathstudent55 Group TitleBest ResponseYou've already chosen the best response.0
Why don't you reduce the 2/8 fraction first?

\(\dfrac{1}{4}x = \dfrac{3}{4}x  6 \)

Now the fractions have a common denominator. Now you can subtract (3/4)x over to the left side.

it gave me 2x=6?

What happened to the denominator of 4? You subtracted 1/4  3/4, not 1  3.

\(\dfrac{1}{4}x  \dfrac{3}{4}x =  6 \) \(\dfrac{2}{4}x =  6 \)
 one year ago

valiyuh Group TitleBest ResponseYou've already chosen the best response.1
oh okay i see and from there i cancel the 2/4x and take it to the other side having 6/2/4 right?
 one year ago

mathstudent55 Group TitleBest ResponseYou've already chosen the best response.0
Now you multiply both sides by 4/2.
 one year ago

mathstudent55 Group TitleBest ResponseYou've already chosen the best response.0
\( \dfrac{4}{2}\left( \dfrac{2}{4}x \right) = \dfrac{4}{2}( 6) \)

Did you get an answer for x?
 one year ago

mathstudent55 Group TitleBest ResponseYou've already chosen the best response.0
Correct.
 one year ago

mathstudent55 Group TitleBest ResponseYou've already chosen the best response.0
After you multiply out the right side, you get x = 12. That's not the final answer of the problem, because the problem asks what is MK.
 one year ago

valiyuh Group TitleBest ResponseYou've already chosen the best response.1
yes thats correct.
 one year ago

mathstudent55 Group TitleBest ResponseYou've already chosen the best response.0
Above, you had written an expression for MK in terms of x. Now you know x, so you can find MK. MK = (1/8)x, and x = 12, so what is MK?
 one year ago

mathstudent55 Group TitleBest ResponseYou've already chosen the best response.0
Yes. MK = 12/8 = 1.5
