    Answer: 11c

    Step-by-step explanation:

    At 5am the temperature was = - 7c.

    In the afternoon (12 noon to 4pm) the temperature = 4c.

    The change in temperature during the day = Final temperature - Initial temperature

    So, change in temperature during the day = 4c - (-7c)

    Recall that minis sign multiply by minus sign becomes plus sign ➕

    So, 4c - (-7c) = 4c + 7c

    = 11c
