Ah! This is so hard!
From midnight to 6:00 am the temperature rose 8 degrees C. At 6:00 am the temperature was -20 degrees C. What was the temperature at midnight?
It's supposed to involve integers...
T + 8 = -20
T = -20-8 = -28o C @ Midnight.
The answer is -28°C.
You're supposed to show your work, too.
Henry put it very nicely so thx Henry
To solve this problem, we need to determine the temperature at midnight. We know that from midnight to 6:00 am, the temperature rose 8 degrees Celsius, and at 6:00 am, the temperature was -20 degrees Celsius.
To find the temperature at midnight, we need to subtract 8 degrees from -20 degrees.
To subtract integers, we can think of it as adding the opposite. In this case, subtracting 8 degrees is the same as adding -8 degrees.
So, we add -8 degrees to -20 degrees:
-20 degrees + (-8 degrees) = -20 - 8 = -28 degrees
Therefore, the temperature at midnight was -28 degrees Celsius.
