Answer:

ST = 4

Step-by-step explanation:

A segment joining the midpoints of 2 sides of a triangle is half the length of the third side.

ST = $\frac{1}{2}$ PQ substitute values

- 32 + 9x = $\frac{1}{2}$ (- 5x + 28) ← multiply both sides by 2 to clear the fraction

- 64 + 18x = - 5x + 28 (add 5x to both sides )

- 64 + 23x = 28 ( add 64 to both sides )

23x = 92 ( divide both sides by 23 )

x = 4

Then

ST = - 32 + 9x = - 32 + 9(4) = - 32 + 36 = 4

kotegsom [21]

Answer:

$\frac{4}{15}$ (4/15)

Step-by-step explanation:

$\frac{4}{6}=\frac{2}{3}$

$\frac{2}{5}*\frac{2}{3};$

1- Multiply the numerators:

$2*2=4$

2- Multiply the denominators:

$5*3=15$

3- Thus:

$\frac{2}{5}*\frac{2}{3}= \frac{4}{15}$

Hope this helps ;)
