Question

At 8 A.M., the temperature was 3°F below zero. By 1 P.M., the temperature rose 14°F and by 10 P.M., dropped 12°F. Plot points and draw arrows on the number line below to model this situation. - 14 - 12-10-8-6-4-2 0 2 4 6 8 10 12 14 What was the temperature at 10 P.M.? Explain how the number line helped you find your answer.

Answer 1

the temperature on the scale is given as follows,

at 10 pm the temperature will be - 1 F

at 8 am the temp is - 3 F as it is given 3 F less than zero

at 1 pm the temp is -3 + 14 = 11 F as it is given that it rose 14 F from -3 F .

at 10 pm the temp is 11 - 12 = -1 F as it is given that it dropped 12 F from 11 F.
