Mr. Noah wants his Ark to sail along an even keel. The ark is divided down the middle, and on each deck the animals on the left exactly balance those on the right all but the third deck.

Can you figure out how many giraffes are needed in place of the question mark so that they(and the lion) will exactly balance the six zebras?

Answer:3

Step-by-step explanation:

Three giraffes are needed in place of lion so that they will exactly balance the six zebras

What is equation?

Equation is the defined as mathematical statements that have a minimum of two terms containing variables or numbers is equal.

Let,

The number of elephants = E

The number of zebra = Z

The number of kangaroo = K

The number of lion = L

The number of giraffes  = G

According to the question,

E +  L+ 2G= 6Z + 2K           ---(i)

E + 2K + 4G = 46                  ---(ii)      

L= 3Z                                  ---(iii)

C = 2 L                            ---(iv)

6Z =  L+G                          ---(v)

From equation (ii) and (iv),    

2K + 4G = 26                        ---(vi)

From equation (i) (iii) and (iv),

2 L+ L+2G= 6Z+2K

3B+2G= 6Z+2K

Where  L= 3Z

So, 9Z + 2G = 2K

From equation (vi) and (vii),    

3Z + 6S +4G = 26

where  L = 3Z  

So, 3Z + 6G = 6Z

6G = 3Z

From equation (iii) and (v),

6Z = 3Z + G

So, G = 3Z

Hence, 3 giraffes are needed in place of lion so that they will exactly balance the six zebras
