First box is EF.
Second box is segment congruence postulate.
Third box is segment additon postulate.
Fourth box is DF. For this one the last sentence basically gives you the answer.
Just so you know for the fourth I guessed on if it's DF lined or DF unlined. I made my educated guess on the fact that the last line doesn't have a line. I hope this helps, and please tell me if I got something wrong, or my explanation wasn't sufficent enough for you.
Is this
-6 ÷ 20 + 150%
or is -6/20 a fraction?
<span>0.833333333333333 is the answer</span>
The pattern is *2 +3 *2 +3 *2 +3 .... 1 *2 = 2 , 2+3 = 5 , 5 *2 = 10, 10 +3 = 13, 13*2 = ?...
The idea for transitions for an equation like this is

where m = slope
h = how much left or right (note the negative)
k = how much up or down
moving 13 down would mean
k = -13
so

D. would be your answer
