Answer:

  x = 4

Step-by-step explanation:

The two marked angles are supplementary when the lines are parallel.

  (20x +5)° +(24x -1)° = 180°

  44x +4 = 180 . . . . . . simplify

  44x = 176 . . . . . . . . . subtract 4

  x = 4 . . . . . . . divide by 44

__

The two angles are ...

  (20·4 +5)° = 85°

  (24·4 -1)° = 95°

How do you graph it on a line
Aleonysh [2.5K]

In order to draw x ≤ -10 on a number line, first draw a closed dot at -10. This is because we have a ≤ and not a <. If we had a <, it would be an open dot.

Next, since we want x to be smaller, draw an arrow pointing towards all numbers that are smaller. This arrow would point to the left.
