Suma a 3 numere naturale este 163. Scazand al treilea numar din suma primelor doua numere, obtinem 67. Scazand primul numar din
Vika [28.1K]

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:

x+y+z=163 (1)

x+y-z=67 (2)

-x+y+z=37 (3)

Let's begin by isolating x from (1):

x=163-y-z (4)

And substitute (4) in (2):

163-y-z+y-z=67 (5)

Isolating z:

z=48 (6) We have found the first number

Substituting (6) in (1):

x+y+48=163 (7)

Adding (7) to (3):

\left \{ {{x+y+48=163} \atop {-x+y+z=37}} \right

We have the following:

2y+96=200

Isolating y:

y=52 (8) This is the second number

Substituting (6) and (8) in (1):

x+52+48=163 (9)

Isolating x:

x=63 (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!

State the Pythagorean Theorem and how would you use it to find a missing side or missing hypotenuse of a right triangle.
Mila [183]

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.
