Answer:
x = 7
Step-by-step explanation:
first subtract 4 from both sides
-3x = -21
divide both sides by negative 3
x = 7
Over this 10-minute interval, the car's average acceleration is

The MVT says that at some point during this 10-minute interval, the car must have had an acceleration of 60 mi/h^2.
Answer:
m∡GHI = 21°
Step-by-step explanation:
Since the lines are intersecting, GHI and JHK are opposite angles, so they are the same measure.
That means you can set them equal to each other
x + 7 = 3x - 21
x = 14
Now plug x into GHI
14 + 7 = 21
m∡GHI = 21°
