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.
