Answer 1

Hey!!

Here is your answer.

(I). Given that temperature was -4 °C in the morning and it went up to 5 °C.
By how many degrees, it rose....
= Risen Temperature - Initial Temperature
= 5 - (-4) = 9 Degrees.
Hence, it rose by 9 Degrees.

(II). Then, it fell by 7 degrees from 5°C.
Then, Resultant Temperature = 5 - 7
= -2 °C.
