Question

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?

A.
x + y = 6
y = 420x

B.
x + 6y = 420
y = 6x

C.
x – y = 420
y = 6x

D.
x + y = 420
y = 6x
Please Help Thank you who ever dose and thi is all one Question :)

Answer 1

Answer:

The answer is D.

Step-by-step explanation:

x + y = 420

y = 6x

Answer 2

The answer would be d , because you have to add how many of each fish to equal up to the sum of 420 . which is x y . so the first equation is x + y = 420 . then it says he bought 6 times as many parrotfish as he did angelfish so you would have to multiply x which represents angelfish by 6 . to get the second equation of y = 6x .
