Rocco gained 64 yards on 16 carries during a recent football game. Find the unit rate of yards per carry.

 4 yards per carry

Step-by-step explanation:

To get  from yards per carry divide the number of carries by itself to reduced  it to one and the same as you will divide the yards by 64 too.

64 = 16  

4 = 1

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.

hope i could ! : )

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
