A plane flew 1,740 km in 6 hours with a tail wind. On the return trip, going into the wind, the plane flew 570 km in 3 hours. What is the plane's speed if there was no wind? What is the speed of the

wind? Write the system of equations that would be used to solve this problem. A.(r + w)6 = 1740
(r – w)3 = 570
B.(r – w)6 = 1740
(r + w)3 = 570
C.(r + w)3 = 1740
(r – w)6 = 570
D.(r – w)3 = 1740
(r + w)6 = 570

C.(r + w)3 = 1740

When solving the system by substitution, what would you plug into the second equation for the letter x?
x+2y=4
2x+2y=6 A.x = 2
B.x = 4-2y
C.x = 4
D.x = 2y+4

Weegy: A.x = 2 User: thanks :) Weegy: You are very welcome! Is there anything else we can help you with? User: If you were to solve the system using the addition method, what would you multiply the first equation by in order to make the x's add out of this system?
-2x + 3y = 6
4x – 2y = 8 A.2
B.-2
C.4
D.none of the above
Weegy: B.-2 User: thanks again sorry im very horrible at math an am trying to help my son in math ... (More)
