Answer:
10.14 feet per year.
Step-by-step explanation:
Given:
Over the next 3 1/2 years, a tree grew to a final height of 35 1/2 feet.
Question asked:
During those 3 1/2 years, what was the average yearly growth rate of the height of the tree?
Solution:
We can find the average yearly growth rate by using average formula, taking
final height of the tree as sum of observation and time span taken to growth as number of observation:-
As we know:
Thus, during , the average yearly growth rate of the height of the tree was 10.14 feet per year
Step-by-step explanation:
z=y+16
y=y
:.z+y=5x where z=y+16
2y+16=5x
x=(2y+16)/5
.:z+y+x=180
y+16+y+(2y+16)/5=180
12y+80+16=900
y=67
z=16+67=83
x=30
Answer:
{10,8}
Step-by-step explanation:
-3x + 4y = -62
4x + 5y = 0
let's eliminate the x
-3x + 4y = -62 | x -4 |
4x + 5y = 0 | x 3 |
12x - 16y = 248
12x + 15y = 0
-------------------- -
-31y = 248
y = 248/(-31) = 8
since you must do this proble with elimination, we cant use subtitution. so we repeat the way once more to find x (eliminate y)
-3x + 4y = -62 | x 5 |
4x + 5y = 0 | x 4 |
-15x + 20y = -310
16x + 20y = 0
-------------------- -
-31x = -310
x = -310/-31 = 10
