An equation is formed of two equal expressions. The value of x is the equation ax-b=c is (c+b)/(a).

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The solution of x in the given equation can be written as,

[tex]ax - b = c\\\\ax = c+b\\\\x = \dfrac{c+b}{a}[/tex]

Hence, the value of x is the equation ax-b=c is (c+b)/(a).

Answer:

The distance around the outside of the track is 4183.58m².

Step-by-step explanation:

The area of running track that goes around the field is 9.76m

To proof :

Formula -

(Area of rectangle = length × breadth)

(Area of running track = outside area - inside area)

First case (outside),

length = 73 +2× 9.76

= 92.52m

Breadth = 84.39 m

radius of outside semi circle,

= 46.26m

outside area = area of rectangle + 2 × area of the semi-circle

= 92.52 x 84.39 + 3.14 x 46.26 × 46 × 26

= 7807.76+6719.56

Second case,

radius of the semi-circle,

=36.5m

inside area = area of rectangle + 2x area of the semi-circle

=73x 84.39+ 3.14x 36.5×36.5

= 6160.47 +4183.27

= 10343.74m²

Now,

Area of running track = 14527.32 m²- 10343.74m²

= 4183.58m²

The distance around the outside of track is 4183.58m².

[tex]\frac{-3}{-26}[/tex]

Step-by-step explanation:

[tex]\frac{-x-8}{x^{2}-4x-21}[/tex] is what you are looking for.

So with x = -5, it would look like this

[tex]\frac{-(-5)-8}{-5^{2}-(-5)4-21}[/tex]

Simple math now.

-(-5) is 5

[tex]-5^{2} = -25[/tex]

-5 * -4 = 20.

So it should be [tex]\frac{5-8}{-25+20-21}[/tex]

5-8=-3

-25+20-21 = -26

So the answer is[tex]\frac{-3}{-26}[/tex]

Answer:

23040 bats

Step-by-step explanation:

Let N(t) be the number of bats at time

We know that exponential function

[tex]y = ab[/tex]

According to question

[tex]N(t) = ab^{2}[/tex]

Where t (in years)

Substitute t=2 and N(2)=180

[tex]180 = ab^{2}[/tex]

Substitute t=5 and N(5)=1440

[tex]1440 = ab^{5}[/tex]

Equation (1) divided by equation (2)

[tex]\frac{180}{1440} = \frac{ab^{2} }{ab^{5}} = \frac{1}{b\frac{5-2}{}}[/tex]

By using the property

Substitute the values of b in equation (1)

Substitute t=9

Hence, after 9 years the expected bats in the colony=23040 bats

Answer:

-1/2

Step-by-step explanation:

Use the two points shown.

slope = rise/run

Start at teh left point.

Go down 2 units. That is a rise of -2.

Now go right 4 units. That is a run of 4.

slope = rise/run = -2/4 = -1/2

Answer:

  97.2 m³

Step-by-step explanation:

The volume of a triangular prism is half the volume of a rectangular prism with the same length, width, and height.

  V = 1/2LWH

  V = 1/2(9 m)(7.2 m)(3 m) = 97.2 m³

_____

Additional comment

The relation we used above comes from the more general formula for the volume of a prism:

  V = Bh

where B is the area of the base.

You know a rectangular base will have an area of ...

  A = bh

and a triangle with the same base and height will have an area of ...

  A = 1/2bh

That is, the base area of a triangle is half that of a rectangle with the same dimensions. When we use this fact in the volume formula, we find the volume of a triangular prism is 1/2 that of a rectangular prism with the same length, width, and height.

Step-by-step explanation:

z = 180° - 113° = 67°

sum of angles of quadrilateral shape = 360°

y = 360° - ( 67° + 81° + 106° ) = 106°

We can simply solve the equations by just dividing by the coefficient value of x. For example, we would divide both sides of the first equation by 8 to make the equation into x = 2/24 = 1/12

8x=2/3 --> x=1/12
1.5=2x --> x=0.75
5x=2/7 --> x= 2/35
1/4x=5 --> x=20
1/5=2/3x --> 3/5=2x --> x=3/10

Calculate the area of the room and then subtract the area of the tiled floor.

area of room = 11 3/4 x 5 = 58 3/4

Area of tiled floor = 7 1/2 x 3 1/4 = 24 3/8

area of carpet = 58 3/4 - 24 3/8 = 34 3/8

answer: 34 3/8
