Answer 1

It is -3 to start off with, on Monday. On Tuesday morning it would be -3 - 2 degrees, = -5 degrees. By Tuesday evening it was 4 degrees lower than in the morning, so -5 - 4 degrees = -9 degrees on Tuesday evening.

Answer 2

The temperature was -9°C on Tuesday evening.

Explanation:

Given,

The temperature on monday = -3°C,

Also, on tuesday morning, the temperature was 2 degrees Celsius lower than it was on Monday,

So, the temperature on tuesday morning = -3°C - 2°C = -5°C,

And, on tuesday evening, the temperature was 4 degrees Celsius lower than it was that morning,

Hence, the temperature on tuesday evening = -5°C - 4°C = -9°C
