Final answer:
The temperature at 7:00 am was -4°C, and after rising 17°C during the morning, the temperature by noon would be 13°C.The correct answer is option C, which is 12 degrees Celsius.
Step-by-step explanation:
The correct answer is option C, which is 12 degrees Celsius.
Let's call the temperature at 7:00am as T1 and the temperature at noon as T2.
Using the given information, we can set up an equation:
T2 = T1 + 17 (change in temperature)
Substituting the values, we get:
T2 = -4 + 17
T2 = 13 degrees Celsius
Therefore, the temperature by noon was 13 degrees Celsius.
If the temperature at 7:00 am was -4°C and the temperature rose by 17°C during the morning, to find the temperature by noon we simply add the increase to the initial temperature. Here's how you do it step by step:
- Start with the initial temperature, which is -4°C.
- Add the temperature rise, which is 17°C.
- Calculate the sum: -4 + 17 = 13°C.
Therefore, the temperature by noon would be 13°C.
