Select the correct answer Jay and Kevin are showing the snow off a driveway. Working together, they can dear the driveway of snow in 14 minutes. Working alone

would take en 21 minutes longer to clear the driveway of snow than it would take jay working alone. When the number of minutes

would take ay to dear the driveway of snow when working alone, the situation is modeled by this rational equation

How long would it take jay to dear the driveway of snow working alone!

7 minutes

Step-by-step explanation:

When Jay and Kevin work together to clear the driveway of snow it takes an average of 14 minutes. If Jay or Kevin works alone to clear the driveway he can clean it in 21 minutes. In total if Jay works alone then he can clean the driveway by spending additional 7 minutes.

2 is the final ! : )

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
