Xian plans to run 14 laps around the track. Each lap is 400 yards. So far, Xian has run 1,680 yards around the track. What percentage of the run has Xian completed?

lockers 1, 4, 9, 16, 25, 40, and 49 are open

i ran through it by the other answer is wrong

so, converting firstly the mixed fractions to improper fractions and then "adding".

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
