How close does the particle come to the nucleus? A car can travel 125 miles in the time a truck can travel 100 miles. If the car's speed is 10 miles per hour faster than the truck's speed, what's the speed of the car and of the truck? Set up an equation to solve it. Three adult movie tickets and two child movie tickets cost exist46. One adult movie ticket and three child tickets cost exist34. How much is the per-ticket cost for an adult movie ticket and for a child movie ticket? Set up a system of equations and solve it. Solve the system of equations by Cramer's rule. x + y = 3, x - y = 1 Solve the system of equations x^2 + y^2 = 6, x^2 - y^2 = 2 The third term of (2x + y) is ax^6 y^2. What's the value of a?
