D.8
A and C are out because they would get you ether lower or equal to 20, which is equal to AC and your trying to find X in AB which is so posed to be the what equals AC+BC.
AB=AC+BC
5x=20+BC
5(8)=20+BC
40=20+BC
40=20+20
AC equals 20. AB will have to equal AC+ CB. If you put in A.4 in AB 5X you will get twenty and that not what you want. You want to get a number that will get you the an answer greater to AC. So 5(8)=40.
Y=1/2x+6
Y-2=1/2(x+8)
Then simplify and get y by itself
Answer:
if she got 4 questions wrong it would be 12
her score if she got x questions wrong it would be 20-2x
Hello ^w^
I believe the answer you are looking for is A
I found this answer by adding up the lengths of all the sides.
S -> T = 8
S -> R = 7
Q -> R = 6
P -> Q = 6
P -> T = 10
10 + 6 + 6 + 7 + 8 -> 37
A -> 37
If I am incorrect, please inform me.
Have a good day!
It is biggest to smallest I presume
