ANSWER:

The aquarium has 3 more yellow fish than green fish.There are 6 green fish in the aquarium.

SOLUTION:

Given, the aquarium has 3 more yellow fish than green fish.  

60 percent of the fish are yellow.  

we need to find how many green fish are in the aquarium?  

Let the number of yellow fish in aquarium be x.

And, the number of green fish in aquarium be y.

Now, according to given information,

x = 3 + y (1)

x = 60% of (x + y)

x = 60/100  × (x + y)

x = 3/5  × (x + y)

5x = 3x + 3y

5x = 3x + 3y

5x – 3x = 3y

2x = 3y

2(3 + y) = 3y  [by using x value in (1)]

2 × 3 + 2 × y = 3y

6 + 2y = 3y

3y – 2y = 6

y = 6.  

Hence, there are 6 green fish in the aquarium.

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29
