Hi, there I'll help you since no one helped you which I felt sad lol, but anyway here's your answer

x=2,y=7→ y=11-2x;4x-3y=-13

x=5,y=2→ 2x+y=12;x=9−2y

x=3,y=5→ y=10+x;-3x+3y=30

x=7,y=3→ x+3y=16;2x−y=11

Hope this helps :)

Answer:

30%

Step-by-step explanation:

Answer:

$151.73

Step-by-step explanation:

No doubt you were given a formula for computing the payment in this situation. You have not provided it here, so we have chosen to use "technology" to find the payment value. A financial calculator or app, or a spreadsheet program can do this computation for you.

_____

We believe the applicable formula to be ...

A = P·(r/12)/(1 -(1 +r/12)^(-18)) . . . . . where r is the annual interest rate; P is the starting balance, and 18 is the number of months over which payments will occur.

Filling in P=2513.77 and r=0.1066, this expression evaluates to ...

A = 2513.77·(.1066/12)/(1 -(1+.1066/12)^-18) ≈ 151.73472 ≈ 151.73
