Yves bought 420 tropical fish for a museum display. He bought 6 times as many parrotfish as angelfish. How many of each type of fish did he buy?

Which is a system of equations to model the problem if x represents the number of angelfish Yves bought, and y represents the number of parrotfish he bought?

(Points : 1)
x + y = 6
y = 420x
x + 6y = 420
y = 6x
x – y = 420
y = 6x
x + y = 420
y = 6x

is the answer D?

Hello?

jhonyy9 · Answer

yes D. is right sure - x+y= 420 yes and you know again that he bought 6 times as many parrotfish as angelfish so y=6x - from these result that choice D. is right sure
