Julie goes to the park across the street from her house several times a day and jogs a total of six miles every day. she jogs three-fourth of a mile at a time. how many times each day does she go to the park to run?

Julie jogs 0.75miles each time. set 'x' to represent the unknown number of times. Total distance for the day is 6 miles. So, you multiply the distance of each run 0.75 times 'x' (unknown number of runs) and set this equal to 6 miles.
0.75x = 6   (divide each side by 0.75)
8 = x 

She ran 8 times each day.

Y=3x+1 so the first one
