L = total lengh, D = number of days
L = 4D + 51 <== ur equation
after 37 days...D = 37
L = 4(37) + 51
L = 148 + 51
L = 199 miles <==
Answer:

Answer:
XY = 16 ft
Step-by-step explanation:
The mid segment DE is half the sum of the parallel bases, that is
= 20 ( multiply both sides by 2 to clear the fraction )
XY + WZ = 40
XY + XY = 40 ( multiply through by 2 to clear the fraction )
2XY + 3XY = 80
5XY = 80 ( divide both sides by 5 )
XY = 16
