Answers
Answer=140 fish
200 gallons of water in the first aquarium.
200 gallons of water in the second aquarium.
The first will be for the small fishes.
5 small fish x fish _____________=__________ 10 gallons 200 gallons
cross multiply 10x=1000 divide both sides by 10 x=100 small fish
The first aquarium has 100 small fish.
The second aquarium holds large fish.
8 large fish x fish ____________=___________ 40 gallons 200 gallons
cross multiply 40x=1600 divide both sides by 40 x=40 large fish
The second aquarium has 40 large fish.
100small fish+40 large fish=140 total fish
In terms of the first aquarium, the number of small fish Skye will have is: 200 gallons of water* (5 small fish/ 10 gallons of water)= 100 small fish.
In terms of the second aquarium, the number of large fish Skye will have is: 200 gallons of water* (8 large fish/ 40 gallons of water)= 40 large fish.
The total number of fish Skye will have is: 100 fish+ 40 fish= 140 fish.

What is the difference of the two polynomials?(7y2 + 6xy) – (–2xy + 3) A7y2 + 4xy – 3 B7y2 + 8xy – 3 C7y2 + 4xy + 3 D7y2 + 8xy + 3
Answers
(7y² + 6xy) - (-2xy + 3)
⇒ (-1 * -2xy) + (-1 * 3) = 2xy - 3
7y² + 6xy + 2xy - 3
7y² + 8xy - 3 Choice B.
B. 7y2 + 8xy – 3 is the answer
