Answer:
Fir trees are 9 meters and the pine trees are 12 meters tall.
Step-by-step explanation:
Let the height of the fir tree = x and the height of the pine tree = y (in meters).
It is given that the combined height of both the trees is 21 meters.
That is, 
Also, the height of 4 fir trees is 24 meters more than that of the pine tree.
That is,
i.e. 
So, we get the system of equations,
x+y=21
4x-y=24
Adding both the equations, gives us,
5x = 45 i.e. x= 9.
So, x+y=21 ⇒ y= 21 - x ⇒ y= 21 - 9 ⇒ y= 12.
Thus, the fir trees are 9 meters tall and the pine trees are 12 meters tall.
62 can go into 584 nine times which will be 558. 584-558=26. Bring down your 1 which will now be 261. 62 can go into 261 four times which will be 248. 261-242=13. So the top answer should be, 94 R 13.
