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:
Step-by-step explanation:
4. A = P + Prt
a. Solve for r
Prt = P - A
r = (P - A)/Pt
b. Solve for t
Prt = P - A
t = (P - A)/Pr
5. Ax + By = C
a. By = C - Ax
y = (C - Ax)/B
b. Ax = C - By
x = (C - By)/A
6. y = mx + b
a. mx + b = y
mx = y - b
x = (y - b)/m
b. mx + b = y
mx = y - b
m= (y - b)/x
c. mx + b = y
b = y - mx
