Respuesta :

1 is a, since the MN would match up with PQ and PR would match up with MO
2  7x - 5 = 5x + 11
2x - 5 = 11
2x = 16
x = 8

Plug x back in
7(8) - 5 = 56 - 5 = 51 so B
Question 1:
Match the order of the letters.
M matches with P, but N does not match with R

Thus, MN≠PR.
So, choice 1 is your answer.

Question 2:
Matching the letters, we know RT = NQ

7x-5 = 5x+11
Add both sides by 5
7x = 5x + 16
Subtract both sides by 5x
2x = 16
Divide both sides by 2
x = 8
Wait! We're looking for the length, not the value of x.
Plug in x = 8 into any of the two equations.

You get 51.
Your answer is the second choice.

Have an awesome day! :)
