There are 40 animals at a petting zoo, all of which are goats or rabbits, and each animal is either an adult or a child. there are twice as many adult rabbits as adult goats, and three times as many child goats as adult goats. if there are an equal amount of adult rabbits as child rabbits, how many adult goats are there at the petting zoo?

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.

idk man good luck man

c = 0.429t

step-by-step explanation:

the constant rate at which carlos harvests cassava is 35 minutes per 15 cassavas 15/35 = 0.429 cassava per minute

therefore, an equation that models the number of cassava (c) that harvest carlos in a time (t) is the following:

where t is the time in minutes.

this means that when 35 minutes have elapsed 15 cassava have been harvested, at 70 minutes 30 cassava have been harvested and so on.
