Q. Yesterday the temperature at noon was 20.4∘F 20.4^{\circ} \mathrm{F} . By midnight, it had gone down by 28.9∘F 28.9^{\circ} \mathrm{F} . What was the temperature at midnight?\newlineAnswer: □\square ∘F { }^{\circ} \mathrm{F}
  1. Identify Initial Temperature: Identify the initial temperature and the temperature change.\newlineThe initial temperature at noon was 20.4°F20.4\degree F, and the temperature decreased by 28.9°F28.9\degree F by midnight.
  2. Calculate Temperature at Midnight: Calculate the temperature at midnight by subtracting the temperature change from the initial temperature.\newlineTemperature at midnight = Initial temperature - Temperature change\newlineTemperature at midnight = 20.4∘F−28.9∘F20.4^\circ\text{F} - 28.9^\circ\text{F}
  3. Perform Subtraction: Perform the subtraction to find the temperature at midnight.\newlineTemperature at midnight = 20.4°F−28.9°F20.4\degree F - 28.9\degree F\newlineTemperature at midnight = −8.5°F-8.5\degree F
