Question

I speak without a mouth and hear without ears. I have no body, but I come alive with wind. What am I? ​

Answer 1

Explanation:

Evaluate the sum of the following integers using the number line:

(i) 7 and 4 (ii) – 3 and 8

(iii) – 18 and 18 (iv) 2, – 3 and – 1

Answer 2

The answer to the above riddle is, "An echo." An echo is a reflection of your own voice. Which is why an echo can 'speak without a mouth and hear without ears'. However, an echo is only heard when the wind conditions are optimal, so it 'comes alive with the wind'.
