Answer:
- <u><em>31 animals</em></u>
Explanation:
The question is in French language. The translation to English is:
<em>1 rabbit saw 6 elephants while going to the river. Each elephant saw 2 monkeys go towards the river. Each monkey holds 1 parrot in its hands.</em>
<em>How many animals are going to the river?</em>

<h2>Solution</h2>

Animal       amount
Rabbit            1
Elephants      6 (the rabbit saw 6 elephants)
Monkeys:       6 × 2 = 12 (2 monkeys per elephant)
Parrots:          12 × 1 = 12 (1 parrot per monkey)
                      =============================
Total:             1 + 6 + 12 + 12 = 31 animals ← answer
 
        
             
        
        
        
I’m going with none because it would just be N-W= blank. Is the blank n or w. I mean it could be one of those but I don’t think you know enough about the question for it to be N or W. So I would say none. Sorry if I’m wrong.
        
             
        
        
        
X° + 123° + 90° = 360° (angles at a point)
x° = 360° - 90° -123°
x° = 147°
The answer of x is 147°
Hope I can help you :)
