Mrs. green puts 57 cans on a shelf. she puts an equal number of cans in each of the 9 rows and puts 3 cans in the last row. how many cans does she put in each of the 9 rows?

Since she has 57 cans and 3 cans are allready devoted to the last row u must do 57-3 in or to get 54 cans total leftover. Then divide the number 54 by 9 since there are nine rows.so i think there will be six cans on each row of the shelf!
 

57-3= 54
54/9= 6
there can be 6 cans on each of the 9 rows

Josephina runs 24 miles

Step-by-step explanation:

Steve and Josephina run a total of 42 miles in a week.

Let S be the number of miles Steve runs

and J be the number of miles Josphina runs

Steve ran six fewer miles than josephina

Total miles is 42

Now we replace S with J-6

Add 6 on both sides

Divide both sides by 2

J= 24

Josephina runs 24 miles
