If we rewrite this equation, it would look like this:

, which is the equation for a straight line with a slope of -4/3 and a y-intercept of 20. The y-intercept exists when x = 0. "x" represents the number of minutes he drives, "y" represents the number of laps he drives. Slope is rise/run, or y/x, which gives us that he drives 4 laps in 3 minutes (the slope of our line). The y-intercept, when x = 0, tells us that when he has driven 0 minutes, or hasn't driven at all yet, he still has 20 laps to go. When y = 0, the x-intercept is

, and

. Multiply both sides by 3 to get that -60 = -4x and that means that x is 15. This means that from start to finish, it takes him 15 minutes to drive the 20 laps.
Answer:
<em>7</em>
Step-by-step explanation:
Sum of angles on a straight line is 180°
12x - 8 + 104 = 180°
12x + 96° = 180°
12x = 180° - 96°
<u>12x</u> = <u>8</u><u>4</u>
12 12
x = <em><u>7</u></em>
