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 :)
The correct answer is d, as it requires adding the quantities of each type of fish, resulting in a total of 420, represented as x plus y. The second equation comes from the fact that he purchased 6 times more parrotfish than angelfish, translating to y being equal to 6x.
Sam needs to score 97 on his upcoming test to keep his average at 85. If you total 63, 84, 96, and 97, the sum is 340. Dividing 340 by four test scores yields an exact average of 85.
From a distance of 300 feet, a car approaches you at a speed of 48 feet per second. The distance d (in feet) of the car from you after t seconds can be described by the equation d=|300−48t|. At what moments does the car find itself 60 feet away from you?
