Dan and Mario went to a sandwich shop to buy sandwiches for their group of friends. Dan bought 2 tuna and 5 vegetarian sandwiches for $37. Mario bought 4 tuna and 3 vegetarian sandwiches for $39. Which system of equations can be used to solve for the cost of each kind of sandwich? 2 x + 5 y = 37. 4 x + 3 y = 39.
2 x + 5 y = 39. 4 x + 3 y = 37.
5 x + 2 y = 39. 4 x + 3 y = 37.
5 x + 2 y = 37. 4 x + 3 y = 39.

you can't solve x because it is 2 linear equation and you only have one equation

no because after the troops were pulled many blacks were killed by hangings lynchings and other cruel ways which in a way interrupted the reconstruction of the south and differed from the way abraham lincoln had an idea of reconstruction

( - 4 , -7 )

all the lines must parallel  

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )
