Write an expression that can be used to solve the problem. . during practice, it took shawn 27 min to swim 81 laps. if shawn swam at a constant rate, how long did it take him to complete each lap? . a.27*81. . b.27+81. . c.81/27. . d.27/81.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
