Answer 3

The quantities in question are 20 feet above sea level and 10 feet below sea level. To determine if they are opposites, we can consider their values on a number line:

• 20 feet above sea level can be represented as +20.
• 10 feet below sea level can be represented as -10.

In order for two quantities to be opposites, their sum must equal zero. Let's calculate the sum:

\[ 20 + (-10) = 20 - 10 = 10 \]

The sum is 10, which is not zero. Therefore, the quantities 20 feet above sea level and 10 feet below sea level are not opposites.

So, in this context, the correct response would be 2, indicating that these quantities are not opposites.
