Answer:
Height of fir tree = 9 meters
height of pine tree= 12 meters
Step-by-step explanation:
The combined height of one fir tree and one pine tree is 21 meters. 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
Subtract x from both sides
height of 4 fir trees = pine tree +24
Substitute 21-x or y in the above equation
Add x on both sides
Divide by 5 on both sides
x=9
Now plug in 9 for x and find out y
y=12
Height of fir tree = 9 meters
height of pine tree= 12 meters

Mean, Median: Is the middle number of the ordered data or the mean of the middle two numbers
Mode: The number or numbers that occur most often
Rage: The difference between the lowest and highest values
Example:
5, 6, 6, 9, 11, 13, 13, 13, 24, 28, 33, 48
Median and Mean: 13
Because is the middle number
Mode: 13
Because is the number that repeats more often
Rage: 43
Because 48 the highest number minus 5 the lowest number equals 43
48-5=43
Answer:
x = 12
Step-by-step explanation:
Lets set up the equation!
Complementary angles equal 90 degrees.
2x + 20 + 3x + 10 = 90
Now lets combine the like terms!
2x + 3x 20+ 10
5x +30 = 90
Now subtract 30 from both sides!
5x = 60
Divide each side by 5
x = 12
