Acar travels 54.9 miles in an hour. if the car continues at theach same speed for 12 hrs how many will it travel

658.8 miles

Step-by-step explanation:

first divide 54.9 by 60. then multiply that by 12 times 60

b. astronomers

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.
