Choose the correct answer.

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.

Answer 1

You'll have to use the same assignment of variables that "they" did

x represents the number of angelfish
y represents the number of parrotfish

Answer 2

So, x + y + ?

Answer 3

Re-read the problem:

Yves bought 420 tropical fish for a museum display.

Answer 4

i think it is B

Answer 5

We are not doing answers yet. We are doing work.

Answer 6

So, x + y = ?

Answer 7

420+6=426

Answer 8

i don't really get it um hold up

Answer 9

x+y=420

Answer 10

How many fish did this dude buy. Look at the question.

Answer 11

he bought 420

Answer 12

Again, >.Yves bought 420 tropical fish for a museum display.

Answer 13

he bought 420 tropcal fish

Answer 14

ok ik that i just get confused on the rest

Answer 15

am i suppose to multiply 420x6?

Answer 16

x+y=420 is the first equation. Now, for the second.

Answer 17

bought 6 times as many parrotfish as angelfish.

Parrotfish = 6*Angelfish

Answer 18

so D

Answer 19

We are not doing answers yet. We are getting the second equation.

Answer 20

x represents the number of angelfish
y represents the number of parrotfish

Parrotfish = 6*Angelfish

Answer 21

y = ?

Answer 22

so it would be y=6

Answer 23

so it would be y=6x

Answer 24

No, that would mean the dude bought 6 parrotfish.
-------------------------------------

He bought 6 times the number of angelfish.

Answer 25

So, y = 6 * ?

Answer 26

x represents the number of angelfish
y represents the number of parrotfish

Parrotfish = 6*Angelfish

as you said

Answer 27

What is the variable for angelfish

Answer 28

so we would replace the parrotfish with y so we get y=6 then we replace the angelfish with x so we would get y=6x

Answer 29

Correct. So, which option is that?

Answer 30

D

Answer 31

That is what I think.
