<span>Krystal's rate = 1 floor in 16 min. = 1/16 floors per min.
Working together their rate = 1 floor in 5.76 min. = 1/5.76 floors per min.
We need to determine Perry's rate, so we need to equate their combined rate with the sum of the individual rates.
Let Perry's time = x
In equation form, we can write:
1/16 + 1/x = 1/5.76
Solve for x:
(x+16)/16x = 1/5.76 -> 5.76(x+16) = 16x -> 10.24x = 92.16 -> x = 9
So, Perry would take 9 mins. to do the floor alone.
I hope this helped!

Answer:
i forgot sorry
Step-by-step explanation:
Set 5x=3x+50 because they are alternate exterior angles. Solve for x and you should get x=25
Next step, plug in the x value for 5x. So 5*25=125. Set y+12=125 since they are vertical angles which are congruent. Solve for y and you get y=113
