Answer: answer is Firts add the two equations to get 11x=22 Then substitute 2 for x in either equation to get y= 1

Step-by-step explanation:so [22][ 2] and ( 1) should be your answers and if your in quiziz mark that is true if ur not then mark my answers

The blank places can be filled as, First, add the two equations to get 11x=22. Then substitute for x in either equation to get y =1.

Inconsistent System

A system of equations to have no real solution, the lines of the equations must be parallel to each other.

Consistent System

1. Dependent Consistent System

A system of the equation to be Dependent Consistent System the system must have multiple solutions for which the lines of the equation must be coinciding.

2. Independent Consistent System

A system of the equation to be Independent Consistent System the system must have one unique solution for which the lines of the equation must intersect at a particular.

The equation can be solved by adding the two of the given equation,

[tex]6x + 2y + 5x - 2y = 8+14\\\\11x = 22[/tex]

As we get the values of 11x=22, find the value fo x which is 2, substitute the equation in either of the given equation,

6x + 2y = 14

6(2) + 2y = 14

2y = 14 - 12

y = 1

Thus, the value of y is 1.

Now, the blank places can be filled as, First, add the two equations to get 11x=22. Then substitute for x in either equation to get y =1.

Answer:

d = 32.73°

Step-by-step explanation:

Angle 'd' is an exterior angle of the given polygon.

By the property of the exterior angles of a polygon, sum of exterior angles of a polygon is 360°.

And the measure of an exterior angle of a polygon = [tex]\frac{360}{n}[/tex]

Here 'n' = Number of sides of the polygon

From the picture attached,

Number of exterior angles of the regular polygon = 11

Therefore, measure of the exterior angle = [tex]\frac{360}{11}[/tex]

                                                                    = 32.7272

                                                                    ≈ 32.73°

Answer:

∠ VXW = 69°

Step-by-step explanation:

The inscribed angle VXW is half the measure of its intercepted arc VW

arc VW = 360° - (116 + 106)° = 360° - 222° = 138°, then

∠ VXW = 0.5 × 138° = 69°

Answer:

21 square feet

Step-by-step explanation:

To find out the area of this irregular figure, divide it into two rectangles and add their areas.. This can be done in two ways.

Version 1: 6 * 2 rectangle and 3 * 3 square

(6 * 2) + (3 * 3)

12 + 9

21 sq. ft.

Version 2: 5 * 3 rectangle + 2 * 3 rectangle

(5 * 3) + (2 * 3)

You could really just do 7 * 3 here.

7 * 3

21 sq. ft.

Either way, you still get 21 square feet as your answer.

Answer:

for kent it would be [tex]\frac{1}{5}[/tex]

Step-by-step explanation:

The computation is shown below:

Let us assume Luannda be [tex]\frac{x}{1}[/tex]

And for kent be 2x

Together they take 5 hours

So

[tex]\frac{x}{1} + \frac{2x}{1} = 5\ hours\\\\3x = 5\\\\x = \frac{5}{3}[/tex]

So for kent it would be [tex]\frac{1}{5}[/tex]

Answer:

Step-by-step explanation:

In order to calculate the volume of a triangular prism you need 2 things:

The triangles area and the prism's height.

Any prism's volume can be calculated by multiplying its base area with its height.

The Area of a triangle can be calculated in different ways.

The most used and "normal" way is:

(width * height) / 2

Another way is by using herons formula, which looks like this:

a, b, c = different sides of the triangle (length)

s = (a + b + c) / 2

a = [tex]\sqrt{s (s-a)(s-b)(s-c)}[/tex]

When you have the prism's base area ([tex]b_{a}[/tex]) you just have to multiply:

[tex]b_{a}*h=V[/tex]

(V = volume)
