Answer

To find the difference between the temperatures on Thursday and Friday, we first note the temperatures:

Thursday: 6 °C
Friday: -3 °C

The difference is calculated as:

$ext{Difference} = ext{Temperature on Thursday} - ext{Temperature on Friday}$

Substituting the values: $ext{Difference} = 6 - (-3) = 6 + 3 = 9$

Thus, the difference between the temperatures on Thursday and Friday is 9 °C.

Step 2

Answer

Given that the temperature on Saturday is 7 °C higher than the temperature on Friday, we start with the temperature on Friday:

Friday: -3 °C

We calculate the temperature on Saturday as follows:

$ext{Temperature on Saturday} = ext{Temperature on Friday} + 7$

Substituting the value: $ext{Temperature on Saturday} = -3 + 7 = 4$

Therefore, the temperature on Saturday is 4 °C.
