Answer:
8
Step-by-step explanation:
2/7 of 21 is 6 1/3 of 21 is 7. 6+7 is 13. 21-13 = 8
So if Bill runs 10 miles in those 4 days then we need to find out Val's.
2 and 3/5. Well, we already know 2*4=8
so 0.6 (which is 3/5) multiplied by 4 is 2.4.
8+2.4=10.4
So here are the results for the distance covered in 4 days :
Val = 10.4 miles
Bill = 10 miles
Therefore, I think Val covers the most distance in 4 days.
Hope I helped :)
THE ANSWER IS: y=3/2x-1/2
first find the slope given the two points
plug in the slope and one of the given point into point intercept form
multiply out the equation to find slope-intercept form
Calculating the unit rate for Tree 2 we have the following

When simplified the unit rate is

This is 2.5 inches per week. Compared to Tree 1,
