Problem Analysis

We are given that there were 120 eggs in the incubator, and some of them hatched into chicks while the rest hatched into snakes. The total number of legs among all the hatchlings is 162. We need to determine how many snakes hatched.

Solution

Let's assume that the number of chicks that hatched is 'x'. Since each chick has 2 legs, the total number of legs contributed by the chicks is 2x.

The remaining eggs, which hatched into snakes, would be 120 - x. Since each snake has 0 legs, the total number of legs contributed by the snakes is 0 * (120 - x) = 0.

According to the problem, the total number of legs among all the hatchlings is 162. Therefore, we can write the equation:

2x + 0 = 162

Simplifying the equation, we get:

2x = 162

Dividing both sides of the equation by 2, we find:

x = 81

Therefore, 81 chicks hatched from the eggs.

To find the number of snakes that hatched, we subtract the number of chicks from the total number of eggs:

120 - 81 = 39

Therefore, 39 snakes hatched from the eggs.

Answer

The number of snakes that hatched is 39.
