The Awnser would be 20.6 rounded up to 21. The final Awnser is 21
With any parallelogram, the diagonals bisect each other. This is another way of saying that they cut each other in half.
FH is one diagonal that is split into two equal pieces by the other diagonal EG.
The two parts of FH (KH and KF) are congruent to each other, so KH = KF. They combine back to FH
By the segment addition postulate
KH + KF = FH
KH + KH = FH .... KF has been replaced with KH (works because KF = KH)
2*KH = FH
Now use substitution
2*KH = FH
2*15 = FH .... replace KH with 15 (since KH = 15)
2*15 = 4x-2 ... replace FH with 4x-2 (since FH = 4x-2)
and solve for x
2*15 = 4x-2
30 = 4x-2
30+2 = 4x-2+2 ... add 2 to both sides
32 = 4x
4x = 32
4x/4 = 32/4 ... divide both sides by 4
x = 8

20x2 = 40 tip
240-40 = 200 rent for 2 busses
240/2 = 100 $ they can spend on each bus rental.
Answer is:
3
Step by step explanation:
2x-1=x+2
or, 2x-x=2+1
or, x=3
PQ = x+2
= 3+2
= 5
