Agym hold a 60 minute time exercise class on saturday a several 45 minute classes during. the week last week all of the classes lasted a total of 285 minutes. write an equation you can use to find the number of the weekday classes

285=45x+60 because 285 stands alone and its you total. 45x is the its there with the variable x because the it says several

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.

the correct answer is $7.38
