    Answer:

    The temperature when Emily went to bed was -4°F.

    Step-by-step explanation:

    8°F + 3°F = 11°F (noon)

    The temperature had risen by 3°F by noon. This means to add 3.

    noon + 6°F = the day’s high temperature

    11°F + 6°F = 17°F (the day’s high temperature)

    The temperature rose another 6°F in the afternoon. This means add 6 to the temperature from noon.

    high temperature – 21°F = temperature at bed

    17°F – 21°F = -4°F

    The temperature dropped by 21°F when Emily went to bed. This means to subtract 21 from the day’s high temperature.  

    Risen, rose, and increase mean addition.

    Decrease, dropped, and decline mean subtraction.

    Hope this helps 🙂
