In sean's fish tank, there are 6 times as many goldfish as guppies. there are a total of 21 fish in the tank. how many more golden fish are there than guppies?

The number of gold fishes which are more than guppies are:

                          15

Let the number of guppies in the fish tank =x

and it is given that:

There are 6 times as many goldfish as guppies.

This means that the number of goldfishes in the tank are: 6x

Also, it is given that:

There are a total of 21 fish in the tank.

i.e.

Hence,

This means that:

There are 15 (18-3=15) more goldfishes in the tank then guppies.

false

step-by-step explanation:

4y - 6 + 4y^2 - 9

before simplifying this contains 4 terms

after simplifying

4y -15 + 4y^2

it contains 3 terms

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
