The temperature on Monday is −4°C. On Tuesday, it is 13° colder. What is the temperature on Tuesday?

17°C

−9°C

−17°C

9°C

The temperature on Tuesday would be -4°C - 13°C = -17°C. Hence, the correct answer is -17°C.

To find the temperature on Tuesday, you need to subtract 13 degrees from the temperature on Monday.

The temperature on Monday is -4°C.

Subtracting 13 degrees from -4°C, we get -4°C - 13°C = -17°C.

Therefore, the temperature on Tuesday is -17°C.
