Answer:

2x+8y=20;y=2

Solution :

{x,y} = {2,2}

System of Linear Equations entered :

[1] 2x + 8y = 20

[2] y = 2

Graphic Representation of the Equations :

8y + 2x = 20 y = 2

Solve by Substitution :

// Solve equation [2] for the variable y

[2] y = 2

// Plug this in for variable y in equation [1]

[1] 2x + 8•(2) = 20

[1] 2x = 4

// Solve equation [1] for the variable x

[1] 2x = 4

[1] x = 2

// By now we know this much :

x = 2

y = 2

We are done

Solution :

{x,y} = {2,2}

Vsevolod [243]

Answer:

D. 5 inches

Step-by-step explanation:

Given:

A frozen dinner is divided into 3 sections on a circular plate with a 12-inch diameter.

That means complete angle having 360° is divided into 3 section.

The central angle formed by the peach cobbler is 105 degrees.

The central angle formed by the pasta is 203 degrees.

Question asked:

What is the approximate length of the arc of the section containing the peas?

Solution:

The central angle formed by the peas = 360° - 105° - 203°

= 52°

$Ridius,r=\frac{Dameter}{2} =\frac{12}{2} =6\ inches$

As we know:

$Length\ of\ arc=2\pi r\times\frac{\Theta }{360}$

$=2\times\frac{22}{7} \times6\times\frac{52}{360} \\ \\ =\frac{13728}{2520} \\ \\ =5.44\ inches$

Therefore, the approximate length of the arc of the section containing the peas are 5 inches.

Name a polygon that would have a

liubo4ka [24]

Answer:

The polygon has 43 sides . The polygon can be called 43 - gon or tetracontakaitrigon.

Step-by-step explanation:

In a regular polygon all the sides are equal and also all the angles are equal. The sum of the interior angle of a polygon can be calculated with the following formula;

sum of interior angle = (n−2) × 180°

where

n = number of sides

The sum of the interior angle should be less than 7500 and greater than 7201.

sum of interior angle = (n−2) × 180°

less than 7500 and greater than 7201 = (43 - 2) × 180

less than 7500 and greater than 7201 = 41 × 180

less than 7500 and greater than 7201 = 7380 °

The polygon has 43 sides . The polygon can be called 43 - gon or tetracontakaitrigon.
