Question

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

Answer 1

Answer:

-11 -3 +5-3 = -12

Step-by-step explanation:

-11°C falls by 3°C= (-11°c-3°c)→ -14°C at 6am

-14°C rises by 5°C = (-14°c+5°c)→ -9°C at 8am

-9°C falls by 3°C=(-9°c-3°c)→ -12°C at 9am
