Okay, strangest thing. I complete forgot how to solve with letters ad the denominator

Answer 5

you just have to cross multiply

Answer 6

multiplying across the diagonals gives us

8*CE = 4*2

solve for CE

Answer 7

8/8?

Answer 8

Or CE/8?

Answer 21

last one needs to be parallel b/c 2/8 = 3/12 which agrees with the proportionality theorem

Answer 22

others are fine

Answer 23

http://prntscr.com/hz0y24 I tried to see if I can set it up correctly myself. May be wrong

Answer 24

hypotenuse/leg = hypotenuse/leg

Answer 25

AD is the left leg
4.5 and 5 are the hypotenuses
4 is the right leg

so

4.5/AD = 5/4

solve for AD

Answer 26
