Find the value of x in each case:
L, M ∈ KN

Find The Value Of X In Each Case:L, M KN

Answers

Answer 1

Answer:

x = 27

Step-by-step explanation:

From the picture attached,

m∠PLM + m∠PLK = 180° [Linear pair of angles are supplementary]

m∠PLM + 3x = 180°

m∠PLM = 180° - 3x

Similarly, m∠PML + m∠PMN = 180° [Linear pair of angles]

m∠PML + (2x + 72)° = 180°

m∠PML = 180° - (2x + 72)°

From triangle PLM.

m∠PLM + m∠PML + m∠LPM = 180° [Sum of interior angles of a triangle = 180°]

(180 - 3x) + 180 - (2x + 72) + x = 180

180 - 3x - 2x - 72 + x = 0

-4x + 108 = 0

x = [tex]\frac{108}{4}[/tex]

x = 27

Mario had 12 apples and gave away x apples. Luigi had 26 apples and gave away three times as many apples as Mario did. How many apples did Mario give away if they had the same number of apples left?​

Answers

Answer:

7 Apples

Step-by-step explanation:

For this question, we can write expressions for Maria's apples and Luigi's apples and form an equation as they end up with the same amount.

Mario starts with 12 apples but gives away x number. This means Mario's final amount of apples can be represented as: 12-x

Similarly Luigi starts with 26 and gives away 3 times the amount of Mario. So the number he gave away can be represented as: 3x (3 times the number Mario gave away). Therefore we can represent Luigi's final number as: 26-3x

Since they both end up with the same number of apples, we can put these expressions equal to each other in an equation to solve for x (the number of apples Mario gave away):

Mario             Luigi

12-x       =      26-3x

12-x=26-3x

Now we just need to move the unknowns to one side and the other terms to the other, combine and solve:

12-x-12=26-12-3x

-x=14-3x

-x+3x=14-3x+3x

2x=14

2x/2=14/2

x=7

Mario gave away 7 apples.

Answer:
x = 29, C

Explanation: We are given that total angle is 90°, or a right angle. This means that the two complementary angles must equal 90° together.

Create the equation:
2x - 4 + x + 7 = 90

Solve algebraically:
3x + 3 = 90
3x + 3 - 3 = 90 - 3
3x = 87
3x / 3 = 87 / 3
x = 29 or C

Answers

Answer:

x = 5

Step-by-step explanation:

2x-1+9x+3=57

2x+9x=57+1-3

11x=55

x= 55/11

x= 5

Answer:

x = 5

Step-by-step explanation:

Simplifying 2x + -1 + 9x + 3 = 57

Reorder the terms: -1 + 3 + 2x + 9x = 57

Combine like terms: -1 + 3 = 2 2 + 2x + 9x = 57

Combine like terms: 2x + 9x = 11x 2 + 11x = 57

Solving 2 + 11x = 57

Solving for variable 'x'.

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

Add '-2' to each side of the equation. 2 + -2 + 11x = 57 + -2

Combine like terms: 2 + -2 = 0 0 + 11x = 57 + -2 11x = 57 + -2

Combine like terms: 57 + -2 = 55 11x = 55

Divide each side by '11'. x = 5

Simplifying x = 5

What is the sum of the measures of the interior angles of the decagon?

Answers

Given parameters:

Number of sides of the regular body  = 10

      A decagon has 10 sides.

Unknown:

Sum of the measures of the interior angles = ?

Solution;

 To find the sum of the interior angles of a decagon; use the expression below:

             Sum of interior angles  =  (n - 2) x 180

where;

  n = number of sides;

So,

         Sum of interior angles  = (10 - 2) x 180 = 1440°

The sum of interior angle of a decagon is 1440°

Answers

Answer:

3 = 0.25 + 0.5d

Step-by-step explanation:

Given that:

Amount charged per hour = $2

Time left before inserting $d = 15 minutes

Total time after inserting $d = 3 hours

Total time of 3 hours = time left by previous driver + hours purchased with $d

$2 = 1 hour

$d = x

2x = d

x = d/2 ; 0.5d

Since 15 minutes is left before inserting $d

15 minutes to hour ; 15/60 = 0.25

Total time of 3 hours = time left by previous driver + hours purchased with $

3 = 0.25 + 0.5d

Veronica is given a rectangular piece of paper. If the length of Veronica's piece of paper is represented by x2 + 6x – 2 and the width is represented by 3x - 5, find the area of the piece of paper.

Answers

Answer:

3x^3 +13x^2 - 36x + 10.

Step-by-step explanation:

Area = length * width

= (3x - 5)(x^2 + 6x - 2)

= 3x(x^2 + 6x - 2) - 5)(x^2 + 6x - 2)

= 3x^3 + 18x^2 - 6x - 5x^2 - 30x + 10

=  3x^3 + 13x^2 - 36x + 10.
