Wall of these ! aaa! you will be the brainiest and get 20

The answer to your question is below

Step-by-step explanation:

1.- 3x + 54 = 5x + 14

   3x - 5x = 14 - 54

   -2x = - 40

    x = 20

2.- I can not see it

3.- Yes, they are paralleles

because 180° = 119 + 61 = 180°

4.-

  180° - 82 - 31 = 67°

  180° - 67 - 98 = 15°

  q = 15°

5.- 100 - x + 30 + 4x + 7x = 180

     10x = 180 - 100 - 30

     10x = 50°

      x = 5

     7x = y

     y = 7(5)

    y = 35°

6.-

        55 + 4x + 2x - 5 = 180

        6x = 180 - 50

        6x = 130

        x = 21.7°

7.-

slope = (1 - 2) / (3 - 0)

     m = -1 / 3

     ( y + 1 ) = -1/3(x - 0)

8.-

9.-

slope = 3/7

P (-14 , -3)

   ( y + 3) = 3/7(x + 14)

10.-

Point (3,2)

A (2, 10)

B (4, 7)

slope = (7 - 10) / (4 - 2)

       m = -3/2

New slope = 2/3

            (y - 2) = 2/3(x - 3)
