Vince went on a 3 day hiking trip. each day, he walked 3/4 the distance that he walked the day before. he walked 83.25 kilometers total in the trip. how far did vince walk on the 1st day of the trip?

36 km.

Step-by-step explanation:

Suppose  he walked n km on the first day .

We create the following equation

n + 3/4 n + (3/4)^2 n = 83.25

n + 0.75n + 0.5625n = 83.25

2.3125n = 83.25

n = 36 km.

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175

correct answer:

b.(19,-2)
