Three printing presses, R, S, and T, working together at their respective constant rates, can do a certain printing job in 4 hou
zmey [24]

Answer:

20(E)

Step-by-step explanation:

Printing press R, S and T are working together at their respective constant rate.

They can do a job for 4 hours.

Let r, s and t be the time for printing press R, S and T to complete the job alone at their respective constant rate.

Rate of printing press R = 1/r

Rate of printing press S = 1/s

Rate of printing press T = 1/t

Rate = job / time

R + S + T = 4

1/r + 1/s + 1/t = 1/4

S + T = 5

1/s + 1/t = 1/5

Substitute 1/s + 1/t = 1/5 in the equation 1/r + 1/s + 1/t = 1/4

1/r + 1/5 = 1/4

1/r = 1/4 - 1/5

1/r = (5 - 4)/ 20

1/r = 1/20

r = 20 hours

It takes the printing press R 20 hours to complete the job alone

Please help!
andrew11 [14]
For the linear system :

r+t = 20 and 5(r+t) = 150

If you sub in the first equation into the second, you will get: 100 = 150, which is incorrect

It means the system does NOT have solutions.

Answer will be the last choice
