Answer:

If x is 24.4 then y will be 70.

Step-by-step explanation:

Add 5x to both sides to isolate y. The equation should be 2y=18+5x

Divide all terms by 2 to get y=9+2.5x

If y is 70, the equation is 70=9+2.5x

Subtract 9 from both sides to get 61=2.5x

Divide both sides by 2.5 to get x=24.4

Lines AB and CD are parallel. If 6 measures (3x - 33)°, and 5 measures 123°, what is the value of x?
Andrews [41]

The value of x from the figure is 30 degrees

<h3>Parallel lines</h3>

Parallel lines are lines that have the same slope and have 0 degrees as the angle between them.

The sum of angle 5 and angle 6 are supplementary. Hence;

m<5 + m<6 = 180

3x - 33 + 123 = 180

3x + 90 = 180

3x = 180 - 90

3x = 90

Divide both sides by 3

3x/3 = 90/3

x = 30

Hence the value of x from the figure is 30 degrees

Coordinates (x, y)

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

Point (7, 0)

Equation y = x - 7

<u>Step 2: Find</u>

  1. Substitute in point [Equation]:                                                                         0 = 7 - 7
  2. Subtract:                                                                                                            0 = 0

Since 0 = 0 is true, then it would be a solution to the equation.
