Answer:

m∠A = 18

Step-by-step explanation:

Formula:

the sum of the interior angles of a triangle is 180.

____________________

According to the formula :

    [tex]m\angle A\ +\ m\angle B\ +\ m\angle C=180[/tex]

⇔ x - 22  +  3x + 19  +  x - 17 = 180

⇔ 5x + (19 - 17 - 22) = 180

⇔ 5x + (2 - 22) = 180

⇔ 5x - 20 = 180

⇔ 5x = 180 + 20

⇔ 5x = 200

[tex]\Leftrightarrow x = \frac{200}{5} \\\Leftrightarrow x = 40[/tex]

Conclusion:

m∠A = x - 22 = 40 - 22 = 18

3a+4c

Answer:

6(3a+4c)

Step-by-step explanation:

GCF = 6

18a/6+24c/6

= 6(3a+4c)

Answer:

Simplifying

6 + -8x = 7x + -9x + -36

Reorder the terms:

6 + -8x = -36 + 7x + -9x

Combine like terms: 7x + -9x = -2x

6 + -8x = -36 + -2x

Solving

6 + -8x = -36 + -2x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '2x' to each side of the equation.

6 + -8x + 2x = -36 + -2x + 2x

Combine like terms: -8x + 2x = -6x

6 + -6x = -36 + -2x + 2x

Combine like terms: -2x + 2x = 0

6 + -6x = -36 + 0

6 + -6x = -36

Add '-6' to each side of the equation.

6 + -6 + -6x = -36 + -6

Combine like terms: 6 + -6 = 0

0 + -6x = -36 + -6

-6x = -36 + -6

Combine like terms: -36 + -6 = -42

-6x = -42

Divide each side by '-6'.

x = 7

The perimeter of the polygon with the vertices L = (1, 4), P = (-1, -2),

N = (2, 0) and M = (4, 0) is approximately 17.93 units.

We have,

The polygon has the following sides:

LP, PN, NM, and ML.

The coordinates for each point are:

L = (1, 4)

P = (-1, -2)

N = (2, 0)

M = (4, 0)

The perimeter of the polygons.

= LP + PN + NM + ML

Using the distance formula for the distance between two points (a, b) and (c, d):

Distance = √((c - a)² + (d - b)²)

Let's calculate the distances between the points:

LP:

Distance(LP)

= √((-1 - 1)² + (-2 - 4)²)

= √((-2)² + (-6)²)

= √(4 + 36)

= √40

= 6.32

PN:

Distance(PN)

= √((2 - (-1))² + (0 - (-2))²)

= √((2 + 1)² + (0 + 2)²)

= √(3² + 2²)

= √(9 + 4)

= √13

≈ 3.61

NM:

Distance(NM)

= √((4 - 2)² + (0 - 0)²)

= √(2² + 0²)

= √4

= 2

ML:

Distance(ML)

= √((4 - 1)² + (0 - 4)²)

= √((4 - 1)² + (-4)²)

= √(3² + 16)

= √(9 + 16)

= √25

= 5

Now,

Perimeter = LP + PN + NM + ML

Perimeter ≈ 6.32 + 3.61 + 2 + 5 ≈ 16.93

Thus,

The perimeter of the polygon is approximately 17.93 units.

The median is 46

Step-by-step explanation:

To find the median, you must first order the numbers, from left to right, lowest to highest:

24, 27, 29, 38, 54, 61, 68, 74

Next, we have to find the number in the middle. We can do this by counting inwards one and crossing out each of the lowest and highest each time we get closer to the middle/center.

24, 27, 29, 38, 54, 61, 68, 74

   ,  27, 29, 38, 54, 61, 68,    

   ,      , 29, 38, 54, 61,      ,    

   ,      ,      , 38, 54,     ,      ,    

Now, if there is no exact middle, we would add them add divide by 2. If there was an exact middle, that would be the answer. But there isn't.

38 + 54 = 92

92 / 2 = 46

The median is 46

Answer:

the second option

Step-by-step explanation:

in ax²+bx+c = 0:

[tex]x = \frac{-b+-\sqrt{b^2-4ac} }{2a}[/tex]

subtract both sides by 6 to get to this form, as the right side will be left with 0

6x² + 8x - 6 = 0

here, the coefficient for x² (a) is 6, the coefficient for x (b) is 8, and the remaining number added on (c) is -6

plugging our numbers into the formula, we get

[tex]x = \frac{-8+-\sqrt{(-8)^2-4(6)(-6)} }{2(6)}\\= \frac{-8+-\sqrt{64-(-144)} }{12} \\= \frac{-8+-\sqrt{208} }{12} \\ = \frac{-8+\sqrt{208} }{12} or \frac{-8-\sqrt{208} }{12}\\= 0.53518375848 or -1.86851709182\\= approximately -1.87, 0.54[/tex]

Answer:

  -20/25

Step-by-step explanation:

To change a fraction to one with a different denominator, common factors can be removed or added to numerator and denominator as required.

__

-48/60 can be reduced to lowest terms by removing the common factor of 12. It can be made to have a denominator of 25 by adding a common factor of 5.

  [tex]-\dfrac{48}{60}=-\dfrac{4\cdot12}{5\cdot12}=-\dfrac{4}{5}\\\\=-\dfrac{4\cdot5}{5\cdot5}=\boxed{-\dfrac{20}{25}}[/tex]

__

Alternatively, the numerator of the desired fraction can be found by multiplying the given fraction by the desired denominator.

  numerator = 25×(-48/60) = -1200/60 = -20

  new fraction = -20/25

Answer:

88%

Step-by-step explanation:

The correct answer is 88% because 12% of the pens are defective.

As a result, 12% ÷ 5000 = 12 ÷ 100 x 5000

= 600

There are 600 defective pens.

The pens that are left are 5000 - 600 = 4400.

4400 pens are in good working order.

This means that 88 percent = 4400 ÷ 5000 x 100
