What are Linear Pair of Angles?

Linear pair of angles are the pair of angles formed when two lines are intersected at a point forming on a line.

Sum of the measures of angles of linear pair is supplementary.

Linear pair of angles are formed on a line.

So we have the pair of angles given, 12x + 19 and 22x - 9 are a linear pair of angles.

They are supplementary angles.

(12x + 19) + (22x - 9) = 180

12x + 22x + 19 - 9 = 180

34x + 10 = 180

34x = 180 - 10

34x = 170

x = 170 / 34

x = 5

Hence the value of x is 5.

Step-by-step explanation:

The value after divide will be 2³ or 8.

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

The expression is,

⇒ 2⁹ divided by 2⁶.

Now,

Since, The expression is,

⇒ 2⁹ divided by 2⁶.

Hence, We get;

⇒ 2⁹ / 2⁶ = 2⁹⁻⁶

              = 2³

              = 8

Thus, The value after divide = 2³ or 8.

Layla has $2 worth of dimes and quarters. She has 6 more dimes than quarters. By
following the steps below, determine the number of dimes, I, and the number of
quarters, y, that Layla has.

Answers

Answer:

Layla has 4 quarters and 10 dimes

Step-by-step explanation:

A quarter each is 25 cents. And a dime each is 10 cents. counts from 10 10 times and then add 25 4 times and you get 200 which is 2 dollars. Example: 10 20 30 40 50 60 70 80 90 100 with 10 dimes alone that's a dollar 4 quarters equal another dollar so both of those equal 2 dollars. Layla had 4 dimes and 4 quarters when she added 6 more dimes it all equaled 2 dollars. Hopefully this makes sense.

Explain how you would find 36x 5/6
mentally.

Answers

Answer:

In step-by-step explanation.

Step-by-step explanation:

Multiplying a fraction (like 1/2) is really just dividing by the denominator.

In this case, we can (mentally) divide 36 by 6.

36/6 = 6

So each 1/6 of 36 is 6.

Then we just add 1/6 of 36 five times to get 5/6

6+ 6+ 6+ 6+ 6 (or 6 x 5) and we get 30.

we will simplify it in four's table

Answer:

x = 18

m<A = 166°

Step-by-step explanation:

The parallel lines are cut by a transversal, so corresponding angles A and B are congruent.

7x + 40 = 3x + 112

4x = 72

x = 18

m<A = 7x + 40 = 7(18) + 40 = 126 + 40 = 166

7x+40 = 3x+112

x=18

7(18)+40

Answer:

  y = 24

Step-by-step explanation:

The line marked 'x' is a midline of the triangle, hence half the length of the parallel base line marked '4x-7'. This lets us solve for x and find the lengths of the sides of the triangle.

  2x = 4x -7

  7 = 2x . . . . . add 7-2x

  3.5 = x

Then the horizontal side of the triangle is ...

  4x -7 = 4(3.5) -7 = 7

The hypotenuse of the triangle is ...

  6x +4 = 6(3.5) +4 = 25

The Pythagorean theorem can be used to find y:

  y^2 +7^2 = 25^2

  y^2 = 625 -49 = 576

  y = √576

  y = 24

The value of y varies directly with x. If x = 15, then y = 12. What is the value of y, when x = 21?
A.26.25
B.16.8
C.0.8
D.1.25

Answers

Answer:

The answers A

Step-by-step explanation:

Use ratios such that x1/y1= x2/y2

Need to find x2

So it works much easier if you use x as the numerator, giving 15/12=x/21

Multiply both sides by 21 and we have 21 x 15/12=x x 21/21

and 21/21=1 giving: x=21 x 15/12= 26 1/4

and in decimal form is 26.25
