1) 4.25/8.5 = 2.5/n  cross multiply

4.25n = 21.25

`(4.25n) / 4.25 = 21.25 / 4.25`

n = 5

2)x=0,1,2,3    y=6,9,12,15

6/0, 9/1, 12/2, 15/3

3)12 yards/day= (    )feet/hour

3 ft in 1 yard

12 x 3 = 36

12 yards/day= 36 feet/24 hour

1.5 ft/h

1) 4.25/8.5 = 2.5/n

4.25n= 21.25

n = 5

2) The slopes are 6/0. 9/1. 12/2. 15/3

3) 12 yards/ day = 36/ 24 feet/hour

= 1.5 feet/hr
