Question

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.

x + y = 420
y = 6x

Answer 6

If I call with \(p\) the number of parrotfish and with \(a\) the number of angelfish, then we can note that:
the statement "He bought 6 times as many parrotfish as angelfish" means that \(p=6a\)
and the statement:
"Yves bought 420 tropical fish" means \(p+a=420\)

Answer 8

Ok I am working it out @Michele_Laino

Answer 9

@Michele_Laino would it be B x+6y=240
y=6x

Answer 10

no, I'm sorry, the second equation is right, whereas the first one is wrong. please keep in mind that \(420\) is the total number of fish, so we can write \(x+y=420\)

Answer 11

Wait a minute let me recalculate

Answer 12

@Michele_Laino Is it C x – y = 420
y = 6x

Answer 13

I think that the first equation is \(x+y=420\)
whereas, the second equation is \(y=6x\)
so, what is the right option?

Answer 14

total number of fish is \(x+y\) not \(x-y\)

Answer 15

SO IT IS D @Michele_Laino

Answer 16

correct!

Answer 17

Yya thank you thank thank you so much @Michele_Laino I got a few more Questions to do.Can you help me on them?

Answer 18

ok!

Answer 19

I can help!

Answer 20

IM GOING WITH D. THIS IS EASY FIRST DIVIDE see what ya get and it says x = blah blah and y = blah soo it's adding too x + y = 420 DOI
