Answer:
14.16 miles further.
Step-by-step explanation:
Campbell to Summerfield
9.52mi + 4.62 mi + 10.08 mi = 24.24 mi
Princeton to summerfield
is 10.08 mi
Therefore difference is 24.24mi - 10.08mi = 14.16 mi
Hope this helps.
Answer:
11 rocks on each shelf x(x+4)-77
Step-by-step explanation:
11*7=77
7 shelves 11 rocks per shelf
Are there choices? If there are, you should list them because there are some equivalents.

I'm assuming that you can solve these things. The top determinant comes to -180. The x value comes to - 540. When divided by the top one x = 3
The bottom determinant (y) comes to 900 and when divided by - 180 makes y = - 5. The checks out with actually solving the system of equations some other way.
We will find the numerator step by step for each expression:
For 10/15 = x / 60
x = (10/15) * (60)
x = 40
For x / 108 = 4/9
x = (4/9) * (108)
x = 48
For 7/11 = x / 121
x = (7/11) * (121)
x = 77
For x / 144 = 2/6
x = (2/6) * (144)
x = 48
