Use back substitution to solve each of the following systems of
equations:
(a)
x1 + x2 + x3 = 8
2x2 + x3 = 5
3x3 = 9
(b)
x1 + 2x2 + 2x3 + x4 =5
3x2 + x3 − 2x4 =1
−x3 + 2x4 = − 1
−x3 + 2x4 =4

Let c be the distance between Carlisle and Wellesley, let b be the distance between Carlisle and Stonebridge, and let a be the distance between Wellesley and Stonebridge.
· If you did a circuit, traveling from Carlisle to Wellesley to Stonebridge and back to Carlisle, you would travel 73 miles.
· The distance from Stonebridge to Carlisle is 12 miles farther than the distance from Wellesley to Carlisle..
· If you drove from Stonebridge to Carlisle and back to Stonebridge, and then continued to Wellesley then back to Stonebridge, you would travel 102 miles.
Write a system of linear equations to represent the situation.
The formula s=√18d can be used to find the speed s of a car in miles per hour when the car needs d feet to come to a complete stop after stepping on the brakes. If it took a car 25 feet to come to a complete stop after stepping on the brakes, estimate the speed of the car. Estimate the value of √18d, when d=25, to the tenths place.
