We know that at 5 am, it was -7 degrees. Since the change of temperature is a negative number, then we subtract the absolute value of the change from -7. -7 - 3 = -10. Following this pattern, we then have: -10 - 2 = -12 (6 am - 7 am) -12 - 5 = -17 (7 am - 8 am) -17 + 6 = -11 (8 am - 9 am, added since it was a positive change of temperature)
Following this pattern, we then have: -10 - 2 = -12 (6 am - 7 am) -12 - 5 = -17 (7 am - 8 am) -17 + 6 = -11 (8 am - 9 am, so it is -11 degrees fahrenheit
