the interior angles formed by the sides of a quadrilateral have measures that sum to 360 degrees. what is the value of x? enter your answer in the box
x =_____

Answer:

30 feet

Step-by-step explanation:

3x8=24 ft

3/4x*8= 6 ft

Answer:

hello

Step-by-step explanation:

adjacent angles are equal to 180 degrees,

[tex](2x + 9) + (5x + 3) = 180 \\ 8x + 12 = 180 \\ 8x = 180 - 12 \\ 8x = 168 \\ x = \frac{168}{8} \\ x = 21 \\ \\ [/tex]

but, for some reason, does not match the answers…

Can the answers be wrong?

or I miscalculated…

i hope it helps have a nice day

Answer:

24

Step-by-step explanation:

(2x + 9 )+ (5x + 3) = 180

x = 24

(I just guessed and checked. It was multiple choice so why not?)

Answer:

45.56923076923077

Step-by-step explanation:

Work out 51.6 x 12 which is 619.2 and subtract that from 1804.80 then x your answer which is 1,184.8 and divide by 26 to get your answer which is 45.569....

Step-by-step explanation:

Random sampling is a sampling method where each sample has an equal chance of being chosen. The random sample chosen is meant to be an unbiased representation of the population.

If 30% of the sample uses the app, it means that 30% of the population are likely to use the app

Answer:

  B' = (18, -16)

Step-by-step explanation:

Dilating means to stretch or shrink a figure. The scale factor tells us how much we are stretching or shrinking. The scale factor is 2, so the coordinates are multiplied by 2.

Answer:

The answer is -2 or C

Step-by-step explanation:

Just input 4 into the equation as x. f(4)=2(4)-10. This gets you 8-10 which is -2. Hope this helps!

Answer:

hey there, person with the same name as me lol. the answer is c. -2

Step-by-step explanation:

in the question they showed that f(x) = 2x - 10

when they ask for the value of any number like f(4)

just replace the variable with this number

for this it will be

2x - 10  = 2 * 4 - 10

which is 8-10

which is equal to -2

you're welcome....

Answer: A and C

Step-by-step explanation:

Answer:

C.

Step-by-step explanation:

The expression equals 0. Because 6+(-6) equals 0 that is the true statement. Enjoy your answer.

Given:

a varies jointly as b and c.

a=6 when b=2 and a=3.

To find:

The variation constant and the equation of variation.

Solution:

a varies jointly as b and c.

[tex]a\propto bc[/tex]

[tex]a=kbc[/tex]              ...(i)

Where, k is the constant of proportionality.

a=6 when b=2 and a=3.

[tex]6=k(2)(3)[/tex]

[tex]6=6k[/tex]

[tex]\dfrac{6}{6}=k[/tex]

[tex]1=k[/tex]

The value of k is 1.

Putting k=1 in (i), we get

[tex]w=1xy[/tex]

[tex]w=xy[/tex]

Therefore, the variation constant is 1 and the equation of variation is [tex]w=xy[/tex].

Answer:

I think the answer would be n = 9/4

Answer:

The answer is below

Step-by-step explanation:

The system of equations:

8x-9y+13z=11

-8x-5y+5z=15

3x+4y-8z=-10

The equations can be represented in matrix form as:

AX = B

X = A⁻¹B

Therefore:

[tex]\left[\begin{array}{ccc}8&-9&13\\-8&-5&5\\3&4&-8\end{array}\right] \left[\begin{array}{c}x\\y\\z\end{array}\right] =\left[\begin{array}{c}11\\15\\-10\end{array}\right]\\\\\\\left[\begin{array}{c}x\\y\\z\end{array}\right]=\left[\begin{array}{ccc}8&-9&13\\-8&-5&5\\3&4&-8\end{array}\right] ^{-1}\left[\begin{array}{c}11\\15\\-10\end{array}\right]\\[/tex]

[tex]\left[\begin{array}{c}x\\y\\z\end{array}\right]=\left[\begin{array}{ccc}\frac{1}{19} &-\frac{1}{19}&\frac{1}{19}\\-\frac{49}{380}&-\frac{103}{380}&-\frac{36}{95} \\-\frac{17}{380}&-\frac{69}{380}&-\frac{28}{95} \end{array}\right] \left[\begin{array}{c}11\\15\\-10\end{array}\right]\\\\\\\left[\begin{array}{c}x\\y\\z\end{array}\right]=\left[\begin{array}{c}-0.74\\-1.69\\0.13\end{array}\right] \\[/tex]

Answer:

.

Step-by-step explanation:

Answer:

-56

Step-by-step explanation:

Let the said number be x, so

x / -8 = 7

That's the equation

On solving further, we cross multiply to have

x = -8 * 7

x = -56

That means the number is -56

Answer:

3k + 9

Step-by-step explanation:

Answer:

The second choice. Because the x-coordinate in the second choice is constant unlike the others, which is a property of a function.

Answer:

Step-by-step explanation:

You want to reverse the algebra and solve for y. First you want to subtract the 'a' to both sides.

x - a = -2by^2

Divide by -1 on both sides

-x + a = 2by^2

Divide by 2b on both sides

(-x + a)/2b = y^2

Take the square root of both sides

[tex]\sqrt{(-x+a)/2b}=y[/tex]

Answer: x=36°

Step-by-step explanation:

The four interior angles of a quadrilateral always equal 360°, so:

(x+16)+(4x-8)+(4x-8)+x=360

Combine like terms:

360=10x+0

360=10x

36=x

Step-by-step explanation:

Answer:

The fraction 4/14 is equal to 2/7 when reduced to lowest terms. To find equivalent fractions, you just need to multiply the numerator and denominator of that reduced fraction (2/7) by the same interger number, ie, multiply by 2, 3, 4, 5, 6

Answer:

$22.40

Step-by-step explanation:

32 - 25.60 = 6.40

6.40/32 = 0.2

0.2 X 100 = 20%

100 - 20 = 80

28/100 X 80 = 22.40
