C. What was the temperature at midnight?
Let x be the temperature at midnight.
From midnight to 6:00 am, the temperature rose 8°C, so at 6:00 am the temperature was x + 8.
At 6:00 am, the temperature was −20°C, so we can write:
x + 8 = −20
Subtracting 8 from both sides, we get:
x = −28
Therefore, the temperature at midnight was −28°C.
To solve this problem, we can use an algebraic equation.
Let's represent the temperature at midnight as "x"°C.
We know that from midnight to 6:00 am, the temperature rose 8°C. This means that at 6:00 am, the temperature was x + 8°C.
Given that at 6:00 am, the temperature was -20°C, we can set up the following equation:
x + 8 = -20
To solve for x, we need to isolate it on one side of the equation. We can do this by subtracting 8 from both sides:
x + 8 - 8 = -20 - 8
This simplifies to:
x = -28
Therefore, the temperature at midnight was -28°C.
Let's denote the temperature at midnight as "x".
We know that from midnight to 6:00 am, the temperature rose 8°C. Therefore, at 6:00 am, the temperature was x + 8°C.
Given that at 6:00 am, the temperature was -20°C, we can set up the equation:
x + 8 = -20
To solve for x, we can isolate the variable by subtracting 8 from both sides of the equation:
x = -20 - 8
Simplifying the right side of the equation:
x = -28
Therefore, the temperature at midnight was -28°C.
