Answer 1

Answer:

x =18 , z =77

Step-by-step explanation:

Vertically Opposite Angles,

[tex]8x - 41 = 7x - 23 \\ 8x - 7x - 41 = - 23 \\ x - 41 = - 23 \\ x = - 23 + 41 \\ x = 18[/tex]

Since angle x and angle 7x-23 lies on the same straight line,

[tex]z + 7x - 23 = 180[/tex]

Substitute x = 18 into the equation,

[tex]z + 7(18) - 23 = 180 \\ z + 126 - 23 = 180 \\ z = 180 - 126 + 23 \\ z = 77[/tex]

What are the steps for 2x+1=7

Answers

Answer:

x = 3

Step-by-step explanation:

Step 1:

Subtract 1 from both sides

2x + 1 = 7

2x + 1 - 1 = 7 - 1

2x = 6

(1 - 1 will cancel itself out on the side with the variable.)

Step 2:

Divide both sides by 2

2x = 6

2x ÷ 2 = 6 ÷ 2

x = 6 ÷ 2

(2 divide by 2, will cancel itself out on the side with the variable.)

Step 3:

Solve for x

6 ÷ 2 = 3

x = 6 ÷ 2 = 3

x = 3

What is the slope m and y-intercept of this image?

Answers

The slope (m) is 1. The y-intercept is 3.
You can use the formula m=y2-y1/x2-x1
When you plug the coordinates in, you get: 3-0/0-(-3)
This leaves you with 3/3, aka 1.
The y-intercept is whatever coordinate on the line makes contact with the y-axis. In this case, it is coordinate (0,3) making the y-intercept 3.

The short sides of a rectangle are 2 inches. The long sides of the same rectangle are three less than an unknown number of inches.

If the area of the rectangle is 22 square inches, what is the value of the unknown number?

Answers

Given:

Short sides of a rectangle = 2 inches.

Area of the rectangle = 22 square inches.

The long sides of the same rectangle are three less than an unknown number of inches.

To find:

The unknown number.

Solution:

Let x be the unknown number. Then the longer side of the rectangle is (x-3) inches.

We know that the area of a rectangle is

[tex]A=length\times width[/tex]

The area of the rectangle is 22 square inches.

[tex]22=2(x-3)[/tex]

Divide both sides by 2.

[tex]11=x-3[/tex]

Add 3 on both sides.

[tex]11+3=x-3+3[/tex]

[tex]14=x[/tex]

Therefore, the value of the unknown number is 14.
