Help me pls :) for my test

D) y=20

Step-by-step explanation:

Given:

4x-4 and 5y+4 are vertical angles (so their measures are the same)

4x-4 and 3x-5 are supplementary angles (so their measures add up to 180°)

Let's find x:

4x-4+3x-5=180

7x-9=180

7x=189

x=27

Since x=27, then y must be:

4(27)-4=5y+4

108-4=5y+4

104=5y+4

100=5y

20=y

y=20

Therefore, the correct option is D) y=20

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
