My Maths investigation! I have a challenge for you to attempt!

Hello there bloggers! I have published my maths investigation, for this week. I found this tricky because finding out which thing it was. The question was....
Some octopuses, fish and a few mermaids are in a rock pool.
Altogether there are 42 arms, 28 eyes and 10 tails in the pool.
How many mermaids are there?

Octopus: 8 arms, 2 eyes, no tails. Fish: 2 eyes, 1 tail, no arms Mermaid:
1 tail, two eyes, 2 arms
How many arms altogether? 8+2=10, 10x (what) = 38     
that would be 3 so that means 3 octopus and 3 mermaids.
There is still 8 left that would add up to one octopus. So 4 octopus and 3 mermaids.
How many eyes? 2x3=6   6x(what)=24 it would be four,
so there would be 4 fish,
How many tails? 1+1=2 2 x (what) = 8 that would be four,
2 of each things that have tails. 2 mermaids and 2 fish.

Mermaid 3+2=5  Octopus: 4 Fish: 4+2=6

I have also a question for the viewers!
