Answer: C.

Mx+Ny=P\\(2M-R)x+(2N-S)y=P-2

Step-by-step explanation:

Given: The system Mx+Ny=P\\ Rx+Sy=T has the solution (1,3), where M,N,P,R,S and T are non zero real numbers.

A.

Mx+Ny=P\\ 7Rx+7Sy=7T

Divide 7 on both sides on the second equation , we will get

Mx+Ny=P\\ Rx+Sy=T

Thus, this system has solution (1,3)

B.

(M+R)x+(N+S)y=P+T.......(1)\\\\ 7Rx+7Sy=7T................(2)

Subtract equation (2) from equation (1), we get

Mx+Ny=P\\ Rx+Sy=T

Thus, this system has solution (1,3)

C.

Mx+Ny=P...........(1)\\\\(2M-R)x+(2N-S)y=P-2T............(2)

We can rewrite the equation (2) as

2Mx-Rx+2Ny-Sy=P-2T............(3)

Multiply 2 on both sides of equation (1), we get

2Mx+2Ny=2P.........(4)

Subtract equation (3) from (4), we get

Rx+Sy=P+2T

But Rx+Sy=T

Thus, this system does not have solution as (1,3).

D.

\frac{M}{2}+\frac{N}{2}=\frac{P}{2}\\\\Rx+Sy=T

Multiply 2 on both sides on the first equation , we will get

Mx+Ny=P\\ Rx+Sy=T

Thus, this system has solution (1,3)

WILL MARK BRAINLIEST!!
Rudik [331]

Answer:

C = (A*P - 8.4Y -330T + 200I) / 100

Step-by-step explanation:

P = (8.4Y + 330T + 100C -200I ) / A

now we have to calculate completed passes C for given P, Y, T, I, A

A*P = 8.4Y + 330T -200I +100C

100C = A*P - 8.4Y - 330T + 200I

C = (A*P - 8.4Y -330T + 200I) / 100

I just solved the equation for C
