Answer:

LM = 57

Step-by-step explanation:

For each median (JN, ML and KP), the distance from a vertex to the centroid is twice the distance from the centroid to the midpoint of the side opposite that vertex.

In that case, LQ = 2QM

If LQ = 38 then QM = 19

38 + 19 = 57

Answer:

$\boxed{x = - \frac{1}{6}}$

Step-by-step explanation:

$= > \frac{1}{2} x + \frac{3}{4} = \frac{2}{3} \\ \\ = > \frac{1}{2} x = \frac{2}{3} - \frac{3}{4} \\ \\ = > \frac{1}{2} x = ( \frac{2}{3} \times \frac{4}{4} ) - (\frac{3}{4} \times \frac{3}{3} ) \\ \\ = > \frac{1}{2} x = \frac{8}{12} - \frac{9}{12} \\ \\ = > \frac{1}{2} x = \frac{8 - 9}{12} \\ \\ = > \frac{1}{2} x = - \frac{1}{12} \\ \\ = > x = 2 \times ( - \frac{1}{12} ) \\ \\ = > x = - \frac{1}{6}$
