Answer:

x = 35

Step-by-step explanation:

we know that all triangles add up to 180

you first need to make an expression in which the angles equal 180

105 + 140 + x = 180

         145 + x = 180

subtract 145 from both sides

                  x = 35

Answer:

66%

Step-by-step explanation:

IT'S D = THE PERCENT DECREASE WAS APPROXIMATELY 66%

The value of angles x,  ∠DEA, and ∠AEB are 14.5, 39.5, and 140.5 degrees respectively.

An angle in Euclidean geometry is composed of two rays that share a common terminal and are known as the angle's sides and vertices, respectively. In the plane where they are positioned, two rays can create angles. When two planes overlap, angles are also created. These are the so-called dihedral angles. The angle formed by the rays that are perpendicular to the two intersecting curves at the point of junction is another property of intersecting curves. The length of an angle or rotation can also be described using the word angle.

Calculations:

Supplementary angles are angles that sum up to 180degrees.

We can see that:

m<DEA + m<AEB = 180

x+25+9x+10 = 180

10x + 35 = 180

10x = 180 - 35

10x = 145

x = 145/10

x = 14.5

Get  ∠DEA

∠DEA = x + 25

∠DEA = 14.5 +25

∠DEA = 39.5 degrees

Get ∠AEB:

∠AEB = 9x+10

∠AEB = 9(14.5) + 10

∠AEB = 130.5 + 10

∠AEB = 140.5 degrees

Answer:

$3

Step-by-step explanation:

The equation we can create for this respective problem is "10x = 30" where the 10 represents the dollars and the 30 represents the tickets. We can start off by dividing each side by 10 since the coefficient is accompanied by a variable, therefore, the inverse would be division. 30/10 equals 3, thus making the answer $3 per ticket.

Hope this helps!  :D

Answer:

One ticket costs 0.333...

Hope this helps

Step-by-step explanation:

10 / 30 = 0.33333...

For example,

If it was 10 tickets for 30$, one ticket would cost 3$. But it is the opposite, it's 30 tickets for 10$.

30 / 10 = 3

Step-by-step explanation:

If you were to graph this, the four points line up with the linear equation.

The distance between the points (2, 4) and (2, -8) on the coordinate plane is 12 units.

The two-dimensional geometric system of a coordinate plane, also called a Cartesian plane, is used to plot and find points using a pair of numerical coordinates.

The formula for calculating distance between two locations in a two-dimensional coordinate plane is as follows:

Distance = [tex]\sqrt((x_2 - x_1)^2 + (y_2 - y_1)^2)[/tex]

where [tex](x_1, y_1)\; and\; (x_2, y_2)[/tex] are the coordinates of the two points.

Using the given points:

Point 1: (2, 4) with [tex]x_1 = 2 \;and \;y_1 = 4[/tex]

Point 2: (2, -8) with [tex]x_2 = 2 \;and\; y_2 = -8[/tex]

Putting these values into the distance formula, we get:

Distance = [tex]\sqrt((2 - 2)^2 + (-8 - 4)^2)[/tex]

Simplifying further:

Distance = [tex]\sqrt(0^2 + (-12)^2)[/tex]

Distance = [tex]\sqrt(0 + 144)[/tex]

Distance = √144

Distance = 12

Answer:

40

Step-by-step explanation:

We're going from 100 to 140 acres. So the change is 140 - 100 = 40.

Based on the division of 6 and 2 over 5 by  negative 4 and 1 over 3, the result would be negative 1 and 31 over 65.

The operation required is to divide 6 and 2 over 5 by  negative 4 and 1 over 3.

As a math expression, this can be shown as:

= 6²/₅ ÷ -4¹/₃

First, make them improper fractions:

= 32/ 5 ÷ -13/3

This can be converted to multiplication as:

= 32/ 5 x -3/13

= 96 / 65

Answer:

y = -1.50x + -3

---------------------------------------------

Step 1: Calculating Slope (m).

m = y2-y1/x2-x1

m = 3-0/-4--2

m = 3/-2

m = -1.50

Now putting value of m in equation (i)

y = -1.50x + b

Step 2: Calculating Y-intercept (b).

Lets choose the first point, (-2,0) for calculating y-intercept:

y = mx + b

0 = -1.50(-2) + b

0 = 3 + b

-3 = b

b = -3

Now putting value of b in equation

y = -1.50x + -3
