Answer: The height of fir tree is 9 meters and the height of pine tree is 12 meters.
Step-by-step explanation:
Given : The combined height of one fir tree and one pine tree = 21 meters.
Since, the height of 4 fir trees stacked on top of each other is 24 meters taller than one pine tree.
Let x be the height of fir tree and y be the height of pine tree.
Then we get the following equations:

Adding (1) and (2) we get

Substitute the value of x in (1), we get

Hence, the height of fir tree is 9 meters and the height of pine tree is 12 meters.

Answer:
The temperature at the base camp Friday evening is - 6 degrees Celsius.
Step-by-step explanation:
To get the temperature at a mountain base camp on Friday evening, we must translate statement into a mathematical form:
(i) <em>The temperature at a moutain base camp was - 2 degress Celsius on Thursday</em>:

(ii) <em>Friday morning, the temperature was 1 degree Celsius lower than it was on Thursday</em>:

(iii) <em>Friday evening, the temperature was 3 degrees Celsius lower that it was that morning</em>:

The temperature at the base camp Friday evening is:
