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?

which system of equations models this problem?

{x−y=405y=8x

{x+y=405y=8x

{x+y=8y=405x

{x+4y=8y=405x

{x+y=405y=8x

{x+y=8y=405x

Step-by-step explanation:

3; 9 is 8 to -4

step-by-step explanation:

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
