The aquarium has 3 more yellow fish than green fish. 60 percent of the fish are yellow. how many green fish are in the aquarium? show your work.

For this case we propose a system of equations:

x: Be the variable that represents green fish

y: Be the variable that represents the yellow fish.

According to the data we have:

We match the equations:

So, there are 6 green fish

6

There are 6 green fish in the aquarium.

Step-by-step explanation:

Let be "g" the number of green fish in the aquarium and "y" the number of yellow fish in the aquarium.

You can set up a system of equations:

Solve for "g" from the first equation and substitute this into the second equation and solve for "y":

Finally, substitute into , then:

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
