The combined height of one fir tree and one pine tree is 212121 meters. The height of 444 fir trees stacked on top of each other

inn [45]

Answer: The height of each fir tree is 9 meters, and the height of each pine tree is 12 meters.

Step-by-step explanation:

Let x= height of each fir tree, y = height of each pine tree.

As per given, we have

x+y = 21 (i)

4x=y+24 (ii)

From (ii),

$4x-y=24$ (iii)

Add (i) and (iii), we get

$5x=45\\\\\Rightarrow\ x=\dfrac{45}{5}\\\\\Rightarrow\ x=9$

Put value of x in (i), we get

$9+y=21\Rightarrow y=12$

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