When Emily woke up, the temperature was 8 degrees F. By noon, the temperature had risen by 3 degrees F. It rose another 6 degree
s in the afternoon to reach the day's high temperature. By the time Emily went to bed, the temperature had dropped 21 degrees F from the high temperature. What was the temperature when Emily went to bed?
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 :)
