The points I, J, K and L all lie on the same line segment, in that order, such that the ratio of IJ:JK:KL is equal to 2:5:5. If IL=60, find KL.

1. are the triangles similar and if so why? what is the value of x? show your work.

Which of these equations, when solved, gives a different value of x than the other three? a9.1 = -0.2x + 10 b10 = 9.1 + 0.2x c10 – 0.2x = 9.1 d9.1 – 10 = 0.2x

10 ! a train starts from grand city and travels toward belleville 388 miles away. at the same time, a train starts from belleville and runs at the rate of 47 miles per hour toward grand city. they pass each other 4 hours later. find the rate of the train from grand city.
