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
Assumed that sides are equal
- 5x-3=3x+1
- 5x-3x=1+3
- 2x=4
- x=2

X = 60 degrees.
A triangle is 180 degrees one side is 30 degrees, and another is 90(right angle)
180 - 30 - 90 = 60
Answer:
<u><em>$4.50 or $4.5</em></u>
Step-by-step explanation:
<em><u>well, this is easy</u></em>

<em><u>so your wondering. What do we do?</u></em>
<em><u>Well, what's 30% of 15?</u></em>
<em><u>It's 4.5</u></em>
<em><u>4 dollars and 5 cents that U will have with Jill.</u></em>
