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, ![x+y=21](https://tex.z-dn.net/?f=x%2By%3D21)
Also, the height of 4 fir trees is 24 meters more than that of the pine tree.
That is,
i.e. ![4x-y=24](https://tex.z-dn.net/?f=4x-y%3D24)
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.
(1/2)/2=3/x
we can cross multiply, aka multiply both sides by 2x
(1/2)x=2*3
(1/2)x=6
times 2/1 both sides
x=12

</h2>
Step-by-step explanation:
Let the mass of the person be
.
Let the spring constant be
.
Let the displacement in spring be ![x](https://tex.z-dn.net/?f=x)
Let the acceleration due to gravity be ![g](https://tex.z-dn.net/?f=g)
As it is given that the person just stands,the forces are balanced.
So,![mg=kx](https://tex.z-dn.net/?f=mg%3Dkx)
Given,
![m=60Kg\\k=2500Nm^{-1}\\g=9.8ms^{-2}](https://tex.z-dn.net/?f=m%3D60Kg%5C%5Ck%3D2500Nm%5E%7B-1%7D%5C%5Cg%3D9.8ms%5E%7B-2%7D)
![60\times 9.8=2500\times x\\x=\frac{588}{2500}=0.2352m](https://tex.z-dn.net/?f=60%5Ctimes%209.8%3D2500%5Ctimes%20x%5C%5Cx%3D%5Cfrac%7B588%7D%7B2500%7D%3D0.2352m)
Answer:
Insert the numbers into the equation y=3x-5.
the rule states that in every equation the first number is x.so it will be -6=3(4)-5
-6=12-5
-6=7.
