Question

fill in the blanks below.
(a) the temperature was 15 degrees below 0 (in fahrenheit) today.
write a signed number to represent this temperature.

(b) a miner dug to a point 1760 feet below sea level.
write a signed number to represent this elevation.

Explanation:

Step1: Analyze part (a)

Temperatures below 0 are represented by negative numbers. So 15 degrees below 0 is $-15$.

Step2: Analyze part (b)

Elevations below sea level are represented by negative numbers. So 1760 feet below sea level is $-1760$.

Answer:

(a) \(-15\)
(b) \(-1760\)
