A car weight 8times more than motorcycle, a motorcycle weight 9 times more than bicycle. If car weight is 1728 than how much is the weight of motorcycle and bicycle.

The motorcycle weighs 216 and the bike weighs 24.

Step-by-step explanation:

C ... car; M... motorcycle; B ... bicycle

C = 1728

A car weight 8 times more than motorcycle. You now make an equation out of this.

C:8=M

1728:8=216

M=216

A motorcycle weight 9 times more than bicycle. You now make an equation out of this.

M:9=B

216:9=24

B=24

instagram is better than go there instead lol

step-by-step explanation:

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.
