The midsegment theorem says that the midsegment is half the third side and parallel as well. 20*2 is 40 so x = 35
To do that we have to add 2+7=9
Next step is to divide 72 by 9
72:9=8 - its how many pounds its in"1"
Finally we can multiply
2*8=16
7*8=56 - its the answer
Answer for the second question:
5*2 is 10
10 *2 is 20
20*2 is 40
40*2 is 80
80 *2 is 160
That's five hours
160*2 is 320
320*2 is 640
640*2 is 1280
1280*2 is 2560
The answer should be 2560
I forgot how to do it with the equation sorry
