4y=7x
The sum of the numbers is 22
so, x+y=22
x=(22-y)
by substitute (22-y) for x in the first equation.
Answer:
El perímetro del triángulo rectángulo es aproximadamente 29.627.
Step-by-step explanation:
Las coordendas de los vértices del triángulo rectángulo son
,
y
. En primer lugar, determinamos las longitudes de los segmentos AB, BC y AC por el Teorema de Pitágoras:
![AB = \sqrt{(-8-1)^{2}+[4-(-2)]^{2}}](https://tex.z-dn.net/?f=AB%20%3D%20%5Csqrt%7B%28-8-1%29%5E%7B2%7D%2B%5B4-%28-2%29%5D%5E%7B2%7D%7D)

![BC = \sqrt{[5-(-8)]^{2}+(2-4)^{2}}](https://tex.z-dn.net/?f=BC%20%3D%20%5Csqrt%7B%5B5-%28-8%29%5D%5E%7B2%7D%2B%282-4%29%5E%7B2%7D%7D)

![AC =\sqrt{(5-1)^{2}+[2-(-2)]^{2}}](https://tex.z-dn.net/?f=AC%20%3D%5Csqrt%7B%285-1%29%5E%7B2%7D%2B%5B2-%28-2%29%5D%5E%7B2%7D%7D)

El perímetro del triángulo (
) es la suma de todos estos segmentos:


El perímetro del triángulo rectángulo es aproximadamente 29.627.
I can't tell if this is what you were asking for, but I included some explanations.
Answer:
42
Step-by-step explanation:
"The Winner." who is Jane, with 70% of the votes, received:
70% of 60 votes
The word "of" usually means multiply.
70% may also be written as 0.70 and as 70/100 (you may choose the one to use)
Let's use (70/100):
(70/100)*60 = 4200/100 = 42 votes
Answer:

Step-by-step explanation:
This sequence is geometric because while x is going up by 1, the y sequence has a common ratio.
That is, term/previous equals same number per consecutive y terms.
So 1/2=2/4=4/8 is the common ratio.
The first term is when x=1. We can find this y by figuring out what we can multiply to our common ratio, 1/2, to get the next term,8.
Since 8(2)=16, then the first term is 16.
In general,

Or if preferred:

where
is first term and
is common ratio.
Plug in information:
