How do you solve this problem. showing work

You can figure out how many boxes Carl will need by dividing the total number of DVDs by the amount of DVDs each box can hold.

Your equation should be: 512 ÷ 20 = x (amount of boxes needed)

512/20 = 25.6

We will round 25.6 up because you cannot have a fraction of a box, so 25.6 becomes 26.

Carl will need 26 boxes.

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
