Answer:

The answer to your question is below

Step-by-step explanation:

I numbered the squares, see the picture below

Angle 3 and the angle given are vertical angles so they measure the same

             angle 3 = 137°

The sum of the angles 1, 2, 3 and 137 equals 360°, so

  angle 1 + 137 + angle 3 + 137 = 360

   and angle 1 and 3 are vertical angles so angle 1 = angle 3

   2angle 1 = 360 - 137 -137

    2 angle 1 = 86

        angle 1 = 86 /2

        angle 1 = 43°

        angle 2 = 43°

The angle given and the angle 5 are corresponding angles, they measure the same

        angle 5 = 137°

Angle 5 and 6 are vertical angles, they measure the same

        angle 6 = 137°

Angle 2 and angle 7 are corresponding angles, they measure the same

        angle 7 = 43°

Angle 3 and angle 6 are corresponding angles

         angle 6 = 137°

Angle 4 and 7 are vertical angle, so they measure the same

         angle 4 = 43°

David bought 3 dvds and 4 books for $40 at a yard sale. Anna bought 1 dvd and 6 books for $18. How much did each dvd and book co
Ber [7]

Answer:

A book is worth $1 and a DVD is worth $12.

Step-by-step explanation:

The equations (2 unknowns and two equations, d is for a DVD and b is for a book):

For David: 3d+4b=40

For Anna: d+6b=18

Now multiply the second equation with -3 and add to the first equation:

3d+4b=40

−3d−18b=−54

Combined equation: −14b=−14 and b=1 (means that each book is worth $1).

 

Now for DVD price, use the second equation:

d=18−6 or d=12 (means that each DVD  is worth $12).

A book is worth $1 and a DVD is worth $12.

Slope-Intercept <br> Find “y” alone<br><br> 2( y - 3 ) = 10x + 4
Anettt [7]

Answer: y = 5x + 5


Step-by-step explanation: Okay follow these steps to get y alone.

2 ( y - 3 ) = 10x + 4

2y - 6 = 10x + 4

2y = 10x + 10

y = 10/2x + 10/2

y = 5x + 5

16 ÷ 22 + (6 x 2) - 8
stepladder [879]
I did the PEMDAS method (P= parentheses, E= exponents, M= multiplication, D = Division, A= addition, S = subtraction.)

First I did what’s inside the parentheses, (6x2) and got 12.

Then I divided 16 by 22 and received 0.72.

I added 0.72 with 12 and the result was 12.72.

Last step was to subtract 12.72 - 8 and that equals 4.72
