Answer 1

Answer: -9°C

Step-by-step explanation:

Given : The temperature in Anchorage, Alaska, was -3°C in the afternoon. After the sun went down, the temperature dropped 6 degrees.

In integers, we use (-) negative sign to show drop in the quantity.

Thus, the integer represents temperature dropped by 6 °C = - 6 °C

Now, the temperature after the sun went down was = -3°C-6°C

i.e. The temperature after the sun went down was =(-3-6)°C

i.e. The temperature after the sun went down was = (-9)°C

Hence,  the temperature after the sun went down was -9°C.

Answer 2

-9 degrees
-3 +(-6) = -9
