Q Q 1. How many solutions does the following system have? 2xty= 4 5x- y =1 O Infinite Solutions O No solution O Two Solutions O One Solution2. A chemist has one solution that is 25% acid and a second that is 50% acid. how many liters of each should be mixed to get 10 L of a solution that is 45% acid? 2- liters of the 25% acid 5 liters of the 50% acid O 7 liters of the 25% acid 3 liters of the 50% acid O 2 liters of the 25% acid 8 liters of the 50% acid O 1 liters of the 25% acid 5 liters of the 50% acid\f[Z] D 4. Solve the following system: y=2x+7l x+y= 13 O(-2,3) O(3,13) O(1,9) O(2,11) [Z] D 5. The sum of two numbers is -45. The rst number minus the second number is 5. Find the numbers. Be sure to show all work including the system of equations created and also work involved to solve the system
