    Answer:

    -18.9 °F

    Step-by-step explanation:

    First, find the temperature at noon:

    -13 + 6.3

    = -6.7

    Then, find the temperature at 3pm:

    -6.7 + 3.9

    = -2.8

    Then, find the temperature at 6pm:

    -2.8 – 16.1

    = -18.9

    So, the temperature at 6pm was -18.9 °F
