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

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

Best ResponseYou've already chosen the best response.0Since M is a bisector, what do you know about the length of JM and the length of KM?

Best ResponseYou've already chosen the best response.1Well 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

Best ResponseYou've already chosen the best response.0Form the figure you see that JM + MK = JK, right?

Best ResponseYou've already chosen the best response.0Great. 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

Best ResponseYou've already chosen the best response.11/8x + 1/8x = 3/4x6 like this?

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

Best ResponseYou've already chosen the best response.0\( \dfrac{1}{8}x + \dfrac{1}{8}x = \dfrac{3}{4}x  6\) Solve for x.

Best ResponseYou've already chosen the best response.1This is the part were im getting confused? Do i add both 1/8x to get 2/8x? or am i wrong?

mathstudent55

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

Best ResponseYou've already chosen the best response.1alright so now i subtract the 3/4 to the other side so now its 2/8  3/4?

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

Best ResponseYou've already chosen the best response.0Now the fractions have a common denominator. Now you can subtract (3/4)x over to the left side.

Best ResponseYou've already chosen the best response.0What happened to the denominator of 4? You subtracted 1/4  3/4, not 1  3.

Best ResponseYou've already chosen the best response.0\(\dfrac{1}{4}x  \dfrac{3}{4}x =  6 \) \(\dfrac{2}{4}x =  6 \)

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

mathstudent55

Best ResponseYou've already chosen the best response.0Now you multiply both sides by 4/2.

mathstudent55

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

Best ResponseYou've already chosen the best response.0Did you get an answer for x?

mathstudent55

Best ResponseYou've already chosen the best response.0After 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.

mathstudent55

Best ResponseYou've already chosen the best response.0Above, 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?

mathstudent55

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