Answer: x=63, y=52, z=48
Step-by-step explanation:
The complete question in english is:
The sum of 3 natural numbers is 163. By subtracting the third number from the sum of the first two numbers, we get 67. By subtracting the first number from the sum of the last 2 numbers, we get 37. Determine the 3 numbers
According to this we have a system with three equations and three unknown values:
(1)
(2)
(3)
Let's begin by isolating 
from (1):
(4)
And substitute (4) in (2):
(5)
Isolating 
:
(6) We have found the first number
Substituting (6) in (1):
(7)
Adding (7) to (3):
We have the following:
Isolating 
:
(8) This is the second number
Substituting (6) and (8) in (1):
(9)
Isolating :
(10) This is the third number

Hey there! :D
1. 7.6 repeating ____ 55 squared
Find 55 squared.
7.6 < 3025
7.6 is less than 7.4.
2. We already know we have 11 as the whole number.
When you have a repeating decimal, you can keep it as a fraction but use 99 as the denominator.
42/99 with the 11 whole number is the answer.
3. -31/6, -5, -5/6, -26^2 <== least to greatest.
-31/6= -5.16667 -26^2= 676
4. I think the 50 is the square root. Everything else can be represented as a fraction or ratio. The square root of 50 is irrational, and cannot be represented by a fraction or ratio. 50 squared is the one that doesn't belong.
I hope this helps!

Answer:
Pythagorean Theorem: A² + B² = C²
You would use it to find a missing side or missing hypotenuse of a right triangle by pluggin in all of the known values of the triangle into the equation and then solving it.
Step-by-step explanation:
C² is the hypotenuse of the triangle (the longest side, and the side that is opposite the right angle).
A² and B² are the remaining two sides.
N and n+2 because if n=1 then you do 1+2 and that equals 3. So then you have 1,3
