Answer:

Number of adult goats = 5

Step-by-step explanation:

Let the numbers of adult rabbits = R

and numbers of child rabbits = r

Let the numbers of adult goats are = G

and numbers of child goats = g

Now we will form the equations as per statements given in the question.

R + r + G + g = 40 -------(1)

R = 2G

g = 3G

R = r ⇒ r = 2G

Now we put these values in the equation 1.

2G + 2G + G + 3G = 40

8G = 40

G = 5

therefore there are 5 adult goats in the petting zoo.
