Need geometry help asap please

x = 20

Step-by-step explanation:

You're in luck I take H geometry.

What I'm going to do is this. 4x - 18 and 3x + 2 are alternate interior angles so they equal the same, so use this equation.

4x -18 = 3x + 2 (add 18 on both sides)

4x = 3x + 20 (minus 3x on both sides)

x = 20

plug in

4(20) - 18 = 3(20) + 2

80 - 18 = 60 + 2

62 = 62

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
