Answer 2

I dont even know where to start

Answer 3

Ostrich = O
Kiwi = K
O = 4K + 20

Answer 4

We work backwards, do the opposite

20 inches MORE than

That's adding 20, so we subtract 20.

WHat's 108 - 20

Answer 5

*What's

Answer 6

Ostrich is 108, so now we have
108 = 4K + 20

Answer 7

Yes, we can also write an equation!

Answer 8

Then work backwards as @iGreen was saying

Answer 9

108 -20 = 88

Answer 10

Yep, so now we have 88 = 4K, divide by 4 and you get K.

Answer 11

Yes, and it says an ostrich is 4 times the size of the kiwi..so we divide 4.

Answer 12

88 \(\div\) 4 :D
