Remark
I hope you don't mind if I laughed a little at the graph. The y intercept of the line is at 10 dollars, but the rental car has not moved an inch. I guess they're charging you to look at your driver's license. It's late, and maybe I am a little giddy.
Begin by using a ruler (or some other straight edge) to join all the dots.
a) I'll spend a little time here. It is very important that you know how to read a chart and this question is your first step. The question is how many dollars does it take to go 40 miles? There is a system. Start with the 40 miles on the horizontal axis (x axis if you know that that is).
Use a ruler to go straight up until you hit the line.
- When you hit the line, mark the place.
- Now move straight across until you hit the y axis where you find out the money.
- You should get 30 dollars.
b) This question is a guess.
- You can find the 70 dollars easily enough. Go straight up again until you hit the line.
- Mark the point on the line.
- Go straight across again.
- Not so easy. It isn't marked. You have to make a guess. My guess is 45. What do you think?
c) This question is the exact reverse of the other two.
- This time you start with the amount of money
- So you start at 60 dollars and go straight across until you hit the line.
- Mark the point.
- Now take your ruler and go straight down.
- You should hit 100 miles.
Answer:
12
Step-by-step explanation:
3 x 12= 36
36-9= 27
7 - (16 - 10) + n = 10
7 - (6) + n = 10
1 + n = 10
n = 9
