Answer:

x = 17, see below for angle measures

Step-by-step explanation:

You're on the right track!

The sum of those two angles inside the triangle equal that opposite angle outside of the triangle. Therefore, you can set them equal to each other.

(4x - 8) + (3x - 16) = 95

Because you are adding the expressions, you can take away the parentheses without changing anything.

4x - 8 + 3x - 16 = 95

Now you want to combine like terms on the left side.

4x + 3x - 8 - 16 = 95

7x - 24 = 95

Combine like terms once again.

7x = 119

Divide to isolate x.

x = 119/7

x = 17

Plug this value back into each expression to find the angle measures.

∠HFG = 4x - 8

∠HFG = = 4(17) - 86

∠HFG = 68 - 8

∠HFG = 60º

∠FGH = 3x - 16

∠FGH = 3(17) - 16

∠FGH = 51 - 16

∠FGH = 35º

∠FHI = 95ª

∠FHG = 180 - 95

∠FHG = 85º

Step-by-step explanation:

We need to do GCF in this case.

2_|_ 24

2_|_ 12

2_|_ 6

3_|_ 3

_|_ 1

|

2_|_ 12

2_|_ 6

3_|_ 3

_|_ 1

|

2_|_ 8

2_|_ 4

2_|_ 2

_|_ 1

|

GCF = what all is common in the sequence.

In every sequence, 2×2 is common.

So, 4 is the answer.

Hope it helps :)

Answer:

y = x + 3

Step-by-step explanation:

Slope-intercept form is represented by the formula [tex]y = mx + b[/tex]. We can write an equation in point-slope form first, then convert it to that form.

1) First, find the slope of the line. Use the slope formula  [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex] and substitute the x and y values of the given points into it. Then, simplify to find the slope, or [tex]m[/tex]:

[tex]m = \frac{(-1)-(3)}{(-4)-(0)} \\m = \frac{-1-3}{-4-0} \\m = \frac{-4}{-4} \\m = 1[/tex]

Thus, the slope of the line must be 1.

2) Now, since we know a point the line intersects and its slope, use the point-slope formula [tex]y-y_1=m(x-x_1)[/tex] and substitute values for [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex]. From there, we can convert the equation into slope-intercept form.

Since [tex]m[/tex] represents the slope, substitute 1 in its place. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of a point the line intersects, choose any one of the given points (either one is fine) and substitute its x and y values into the equation, too. (I chose (0,3).) Finally, isolate y to find the answer:

[tex]y-3=1(x-0)\\y-3 = x\\y = x + 3[/tex]

Answer:

-1

Step-by-step explanation:

2x² - 5x + 7 is subtracted from x² + 2x - 11, so

(x² + 2x - 11) - (2x² - 5x + 7)

x² + 2x - 11 - 2x² + 5x -7 (Distribute the negative)

-x² + 7x - 18 (Combine like terms)

The leading coefficient is the coefficient of the first term, so it is -1.

Answer:

14

Step-by-step explanation:

this is a 30-60-90° Δ and the sides, respectively, have the ratio of 1 : [tex]\sqrt{3}[/tex] : 2

we can set up a proportion and cross-multiply based on that ratio:

w / 7[tex]\sqrt{3}[/tex] = 2 / [tex]\sqrt{3}[/tex]

[tex]\sqrt{3}[/tex]w = 14[tex]\sqrt{3}[/tex]

w = 14

Answer:

2y-x = -8

Step-by-step explanation:

The equation if a line ilin point slope form is expressed as;

y-y0 = m(x-x0)

M is the slope

(X0,y0) is the point

Substitute

y - (-2) = 1/2(x-4)

y+2 = 1/2(x-4)

2(y+2) = x-4

2y+4 = x-4

2y-x = -8

Hence the required equation is 2y-x = -8

Answer: attending the game

Step-by-step explanation:

Given: 12 out of the first 48 people who entered the stands were wearing a coat.

That means, Proportion of people wearing coat = [tex]\dfrac{12}{48}=\dfrac{1}{4}[/tex]  (People wearing coat divided by Total people)

Total people in the sample attending the game= 200

Number of people wearing a coat = [tex]200\times\dfrac14[/tex]

[tex]=50[/tex]

Hence, 50 people are wearing a coat.

Answer:

28°

Step-by-step explanation:

Let's take 'x' as the number of how much degrees it dropped. So this is how the equation will look like:

-2 - x = -30

It is '-x' since the temperature 'decreased', so you must a subtract.

Take -30 to the other side and substitute it with '-x'. Since both the terms are shifted, -30 will be +30 and -x will be +x (which is equivalent to x).

x = -2 + 30

x = 28°

∴ There was a 28° drop.
