I supposed to graph my answer to depict the variables in my situation.
This is my situation:
We were traveling to the valley over the weekend, after traveling 50 miles at a constant speed for 1/2 hour we were pulled over by a state trooper and wrote us a ticket for speeding. How fast were we traveling?

x= 100 mph

Question 88127: It has been a long time since I've been in school and I don't remember the rules for double inequalities within an equation. I'm trying to help my nephew with this problem (he is in Colorado and I'm in California and since it is late I don't have his textbook information).
-3 <= x <= -1
I think you would add 3 to each side (but I'm not sure if you add it in the middle as well): 3-3 <= x <= -1 + 3: 0<=x<=2 which would be x >= 0 and x <=2, but I'm just not sure if this is correct. Please help!
