Determine if the given ordered pair is a solution to the system of linear equations.

choose yes or no for each ordered pair and system of equations.

ordered pair: ( 7, 6)

system of equations:

2x + y = 20

6x - 5y = 12

For 1st equation: 2(7)+6 = 14+6 = 20 = R.H.S

For 2nd equation: 6(7)-5(6)= 42-30 = 12 = R.H.S.

So, your answer is "YES" for both system of equations.

First find total minutes by multiplying 15 minutes by 19 clients:

19 x 15 = 285 total minutes

1 hour = 60 minutes.

Divide total minutes by 60:

285/60 = 4.75 hours ( 4 hours and 45 minutes)
