20/36 reduced is 5/9. hope this helped! :)
Answer:

Step-by-step explanation:
A is on the same point on the x-axis as B and the same point on the y-axis as D
- Therefore, the coordinate of A is (0,0)
C is on the same point on the x-axis as D and the same point on the y-axis as B.
- Therefore, the coordinate of C is (a,a)
We are to determine the slope of the line joining A to C.


The answer would be 40 days
We achieve this answer by dividing the distance of the trip, 30 miles, by the distance traveled per day, 3/4 miles.
7/8 because 3/4 = 6/8, and 7/8 is bigger than 6/8
