A warehouse has 5 shelves long enough to hold 7 boxes and high enough to hold 4 boxes. All the shelves are full. How many boxes are there?

140 boxes

Step-by-step explanation:

7 groups of boxes can be stacked 4 times on each shelf.

7 *4= 28

28 boxes could fit on each shelf. There are 5 shelves.

28*5= 140 so 140 boxes in total.

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.
