Question

The temperature on a certain morning is -11℃ at 5 a. m. If the temperature drops 3 degree at 6 a.m. and rises 5 degree at 8 a.m. and again drops 3 degree at 9 a.m. What is the temperature at 9 a.m.? Explain

Answer 1

Answer:

temperature at 5 = -11 degrees Celsius

temperature at 6=-11-(+3)=-11-3=-14 degrees Celsius

temperature at 8=-14+(+5)=-14+5=9 degrees Celsius

temperature at 9=-9+(-3)=-9-3=-12 degrees Celsius

so the temperature at 9 will be 12 degrees Celsius
