Which system of equations models this problem? the variable x represents the number of angelfish carlos bought and the variable y represents the number of parrotfish he bought. carlos bought 405 tropical fish for a museum display. he bought 8 times as many parrotfish as angelfish. how many of each type of fish did he buy?
{x+y=405 y=8x
{x+4y=8 y=405x
{x−y=405 y=8x
{x+y=8 y=405x
i think d is that right

{x+y=405 y=8x

Step-by-step explanation:

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
