From midnight to 6:00 am, the temperature rose 8°C. At 6:00 am, the temperature was
−
20
°
C. What was the temperature at midnight?
Step 1: Let x represent the temperature at midnight.
Step 2: From midnight to 6:00 am, the temperature rose 8°C. So, at 6:00 am, the temperature would be x + 8°C.
Step 3: At 6:00 am, the temperature was -20°C. Therefore, we can set up the equation:
x + 8°C = -20°C
Step 4: To isolate x, we need to subtract 8°C from both sides of the equation:
x + 8°C - 8°C = -20°C - 8°C
x = -28°C
So, the temperature at midnight was -28°C.
Let's assume the temperature at midnight as x°C.
From midnight to 6:00 am, the temperature rose 8°C. So at 6:00 am, the temperature was x°C + 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'll subtract 8 from both sides of the equation:
x = -20 - 8
Simplifying, we get:
x = -28
Therefore, the temperature at midnight was -28°C.
We can solve this problem by setting up an equation to represent the information given. Let's use 'x' to represent the temperature at midnight.
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.
We also know that at 6:00 am, the temperature was -20°C. So we can set up the equation:
x + 8 = -20
To solve the equation, we need to isolate the variable 'x' by subtracting 8 from both sides:
x = -20 - 8
Simplifying:
x = -28
Therefore, the temperature at midnight was -28°C.
