ZONK Review 1. Find the solution to the following system of equations by graphing: −4𝑥 + 𝑦 = −5 𝑦 = 4𝑥 + 3 3. Solve the following system using SUBSTITUTION. −2𝑥 + 6𝑦 = −8 9 𝑥 = 2𝑦 + 3 2. Graph the system of inequalities and name three points in the solution set. 𝑥≤2 6𝑥 − 3𝑦 < 12 4. Solve the following system using ELIMINATION. 6x – 5y = 76 -3x + 5y = -43 5. There are 400 turtles competing in the Turtle Grand Prix. It cost each turtle $20 to register for the 5k race and $35 to register for the 10k race. If the Turtle Grand Prix brought in $10,340 in registration fees, how many turtles ran each distance? 6. Turtles who signed up for the annual Turtle Grand Prix for the very first time received three free T-shirts. Those turtles who were returning runners only received one free t-shirt. The difference between the number of first time runners at the 5k and the number of returning runners was 60. If they gave away a total of 548 free t-shirts, how many turtles were first time runners? 7. Solve the following system using SUBSTITUTION. 3x + y = 8 4x + 6y = 6 8. Solve the following system using ELIMINATION. -3x + 3y = 12 4x + 2y = 20 9. Spectators at the Turtle Grand Prix can purchase Turtle Trax Ice Cream Cones at the concession stand. The difference between the price of the waffle cone and the price of the regular cone is $0.75. If a family of seven purchased three waffle cones and four regular cones for a total of $28.50, how much was the cost of a single waffle cone? 10. Find the solution to the following system of equations by graphing: 1 4 1 𝑥 + 4 𝑦 = −1 3𝑦 = 𝑥 11. Graph the system of inequalities and name three points in the solution set. 3 −𝑥 + 2 𝑦 > −3 𝑦 ≤ −𝑥 Directions: Solve the following systems using SUBSTITUTION OR ELIMINATION. 12. 3x + 4y = 9 4y – 3x = -1 13. 3x + 4y = 2 9x + 12y = 6 14. Tammy Turtle is going to the concession stand with 11 coins that total exactly $2.00. If her coins are all quarters and dimes, how many of each coin does she have? 15. The race is on! Tony the Turtle got a good start. He has already gone 11 feet, and he is currently traveling at a rate of three feet per minute. Tammy the Turtle woke up late and is just now starting the race, but she’s determine to catch up and is traveling at a rate of 3.5 feet per minute. How many minutes will it take for Tammy to Catch up to Tony? How far will they have traveled at that time?
