X should equal negative 51

1.The sum of three consecutive numbers minus 12 is 75
2. The Sum of two consecutive odd numbers plus eighteen is 170

Answers

Answer:

The answer is

One:   28, 29, 30

Two: 75,77

Step-by-step explanation:

One

Let the three numbers be (x - 1) , x , and x + 1

(x - 1) + x + (x +1 ) - 12 =  75                Remove the brackets

x - 1 + x + x + 1 - 12 = 75                    Combine the like terms on the left

3x - 12 = 75                                       Add 12 to both sides

3x = 75 + 12

3x = 87                                              Divide by 3

x = 87/3

x = 29

Two

Let the first odd number = 2x -1

Let the second odd number = 2x + 1

2x - 1 + 2x + 1 + 18 = 170           Combine like terms on the left.

4x + 18 = 170                             Subtract 18 from both sides.

4x = 170 - 18                             Combine like terms on the right

4x = 152                                     Divide by 4

4x/4 = 152/4

x = 38

2 * 38 - 1 = 75

2 * 38 + 1 = 77

The measures of the angles of a triangle are shown in the figure below. Solve for x.

Answers

Answer:

57 degrees! : D

Step-by-step explanation:

Every triangle angles(all of them) add up to 190 degrees.

so 33+x+90 degrees.

Why do we add 90 degrees? because there is a little "square on the bottom right explaining that it is a 90-degree angle.

so 33+90=123

so x=180(our original sum) minus 123

and so x=57 degrees

It should be 57 because there’s a right angle and a 33 degree angle. 90 from the right angle and 33 is 123 and it all has to equal 180


Answer is 57

Answer:

x = 8

Step-by-step explanation:

Interior angles of a triangle always add up to 180 degrees.

50 + 76 + ? = 180

? = 180 - 126

? = 54

A straight line also is always 180 degrees.

54 + 15x + 6 = 180

15x = 180 - 60

15x = 120

x = 8

Answers

Answer:

The value of the angle x is 140°

Step-by-step explanation:

In the given figure

∵ The figure has 4 sides

∴ The figure is a quadrilateral

∵ The measure of the interior angle of the quadrilateral is 360°

∴ The sum of the angles inside the quadrilateral = 360°

∵ One of the vertices of the quadrilateral has an exterior angle of

   measure 90°

∵ The sum of the interior angle and the exterior angle at a vertex = 180°

∴ The measure of the interior angle = 180° - 90°

∴ The measure of the interior angle = 90°

∵ The measures of the interior angles of the quadrilateral are 60°, 70°,

    x, 90°

∴ 60° + 70° + x + 90° = 360°

→ Add the like terms in the left side

∴ 220° + x = 360°

→ Subtract 220 from both sides

∴ 220 - 220 + x = 360 - 220

∴ x = 140°

∴ The value of the angle x is 140°

What is Interval?

In mathematics, an interval is expressed in numerical terms. All the numbers between two specific integers are referred to as an interval. All actual values between those two are included in this range.

Given:

For the interval 6 < x < 8 the function is decreasing.

Now, For the interval 10 < x < 14 the function is neither increasing nor decreasing.

Now, For the interval 8 < x < 10 the function is increasing.

Now, For the interval 4 < x < 6 the function is increasing.

Now, For the interval 1 < x < 4 the function is decreasing.
