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

Nataly [62]

Answer:

3/4

Step-by-step explanation:

We can find the slope using two points

( 0,-5) and ( 4,-2)

The slope is given by

m = ( y2-y1)/(x2-x1)

   = ( -2- -5)/( 4-0)

    = (-2+5)/(4-0)

A two-dimensional shape is rotated to form the solid object shown in the figure. This two-dimensional shape can be created by ro
Kruka [31]

Answer:

1) Trepzoid

2) Hexagon

Explanation:

A two-dimensional shape is rotated to form the solid object shown in the figure. This two-dimensional shape can be created by rotating a <u>trapzoid</u> about its base. Another two-dimensional shape that can give this shape is a <u>hexagon</u> rotated about a line joining two opposite vertices.

Trapzoid: It is figure whose two sides are parallel and other two sides are non-parallel. Please take a look attachment for trapzoid. If we rotate trapzoid with longer parallel side we will get same 3-D figure as shown in diagram.

hexagon: It is polygon which has six sides. If we rotate hexagon with their opposite vertices. we will get same 3-D figure as shown in diagram. Please see the attach file.
