A lamp post casts an 18ft shadow. If Chris’s shadow is 6ft long and his height is 5.25ft, what is the height of the lamp post?

15.6

Step-by-step explaination:

So first you have to find how much longer the shadow is from the actual. That is 1.15384615385 or about 1.15.

You take that and divide it by 18 and you get 15.6

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.
