You wanna write an equation to find out what the two lengths will be. Because the string in 17 feet the equation has to equal 17. Then for the shorter length you need to symbolize it with a variable (x). For the longer side it is the smaller number plus five(x+5).
Therefore, the equation is x+(x+5)=17
from there you get x= 6ft which leaves the longer side equaling 11ft
If you have 12 dollars and you buy 3 paper back books, they each cost the same amount. So you would divide 12 dollars among 3 books to get the same answer for all of them. 12 divided by 3 equals the answer.
Then if you have 28 dollars and you buy 7 paper back books, they all cost the same amount. So that would be 28 divided by 7, equals the same answer.
