Answer:
![5 = 19 - 4v](https://tex.z-dn.net/?f=5%20%3D%2019%20-%204v)
Step-by-step explanation:
We are given the following in the question:
![\text{Lyle's height} = 2( \text{Harry's height - Vince's height})](https://tex.z-dn.net/?f=%5Ctext%7BLyle%27s%20height%7D%20%3D%202%28%20%5Ctext%7BHarry%27s%20height%20-%20Vince%27s%20height%7D%29)
Let l be Lyle's height, h be Harry's height and v be Vince's height.
Thus, we can write:
![l = 2(h-v)](https://tex.z-dn.net/?f=l%20%3D%202%28h-v%29)
Lyle's Height =
![2\dfrac{1}{2}\text{ feet}](https://tex.z-dn.net/?f=2%5Cdfrac%7B1%7D%7B2%7D%5Ctext%7B%20feet%7D)
Harry's height =
![4\dfrac{3}{4}\text{ feet}](https://tex.z-dn.net/?f=4%5Cdfrac%7B3%7D%7B4%7D%5Ctext%7B%20feet%7D)
Putting the value in the equation:
![2\dfrac{1}{2} = 2(4\dfrac{3}{4}- v)\\\\\dfrac{5}{2} = \dfrac{19}{2} - 2v\\\\5 = 19 - 4v\\4v = 19-5\\\\v = \dfrac{14}{4}\\\\v = 3\dfrac{2}{4} = 3\dfrac{1}{2}](https://tex.z-dn.net/?f=2%5Cdfrac%7B1%7D%7B2%7D%20%3D%202%284%5Cdfrac%7B3%7D%7B4%7D-%20v%29%5C%5C%5C%5C%5Cdfrac%7B5%7D%7B2%7D%20%3D%20%5Cdfrac%7B19%7D%7B2%7D%20-%202v%5C%5C%5C%5C5%20%3D%2019%20-%204v%5C%5C4v%20%3D%2019-5%5C%5C%5C%5Cv%20%3D%20%5Cdfrac%7B14%7D%7B4%7D%5C%5C%5C%5Cv%20%3D%203%5Cdfrac%7B2%7D%7B4%7D%20%3D%203%5Cdfrac%7B1%7D%7B2%7D)
Thus, Vince's height is 3.5 feet.
Answer:
20
Step-by-step explanation:
These are vertical angles, which means that the measurements would be the same. Set the two angles equal to each other.
3x + 50 = 6x - 10
Isolate the variable, x. Subtract 6x and 50 from both sides.
3x (-6x) + 50 (-50) = 6x (-6x) - 10 (-50)
3x - 6x = -10 - 50
Simplify.
-3x = -60
Isolate the variable, x. Divide -3 from both sides
(-3x)/-3 = (-60)/-3
x = -60/-3
x = 20
20 is your answer for x.

I’m not sure what it is but have to answer it
Yes you can classify by sides but I’m not sure about angles
Answer:
The percent increase in the perimeter is 337.5%
Step-by-step explanation:
The easiest way to approach this problem is by using consecutively the simple rule of three.
If the first triangle has sides of length two then, we can compute the second triangle's sides length as follows:
2 units------100%
X units------150%
this way
.
Now for the third triangle we repeat the same process
3 units------100%
X units------150%
getting that the length of the sides for the third triangle is
.
Now for the last triangle we repeat the same process
4.5 units------100%
X units------150%
getting that the length of the sides for the last triangle is
.
Now, we need to know the perimeter of the first and last triangle. This can be calculated as the sum of the length of the sides of the triangle.
For the first triangle
![P_{first}=2+2+2\\P_{first}=6](https://tex.z-dn.net/?f=P_%7Bfirst%7D%3D2%2B2%2B2%5C%5CP_%7Bfirst%7D%3D6)
and for the last triangle
.
To compute the percent increase in the perimeter from the first to the fourth triangle we will use one last simple rule of three (this time the percentage will be the variable)
6 units------100%
20.25 units------X%
so
.
