A midpoint lies right in the middle so this splits the segment into two equal halves.
ST = TU
Let's plug the expressions from the picture into our equation.
8x + 11 = 12x - 1
Add 1 to both sides, and subtract 8x from both sides.
12 = 4x
Divide both sides by 4
3 = x

Explanation:
BC = 78 is parallel to the midsegment DE.
This parallel midsegment is half as long as BC, so DE = BC/2 = 78/2 = 39
-------
DF = 34 doubles to AB = 2*DF = 2*34 = 68, since the midsegment is half as the parallel side, so we just think in reverse of that process.
-------
BE = 34 for two reasons
- Quadrilateral EBFD is a parallelogram with opposite sides BE and DF that are congruent.
- E is the midpoint of AB, so BE is half as long as AB
--------
We don't use the info that AC = 48.
3 + 2k
This is because multiplying by 1/5 is like dividing each term by 5
i think it is 1.5 percent just divide
