Answer:
a)
Thus, there are 22 minutes per lap
b)
Thus, there are 0.5 laps per minute
c)
If Lin runs 21 laps at the same rate, it would take 42 minutes to do so.
Step-by-step explanation:
Lin runs 5 laps around a track in 10 minutes.
i.e. 5 laps in 10 minutes.
so
5/10 = 1/2 laps per minute
- unit rate = 0.5 laps / per minute
a)
Thus, there are 22 minutes per lap
b)
Thus, there are 0.5 laps per minute
c)
Unit rate = 0.5 laps per minute
If Lin runs 21 laps at the same rate, it would take 42 minutes to do so.

Answer:
2x-1 is an equivalent answer.
Multiply the first bracket by -4. Multiply the second bracket by -2
-8x+12y+4x-2x-12
Negative and Negative = Positive
Negative and Positive = Negative
Then do -8x+4x-2x
= -6x+12y-12
Answer is D. -6x+12y-12
