week 2 Solve the system of equations; 1. -7x-8y=2 5x-3y=16 X= Y= 2. The sum of two numbers is 36. The smaller number is 20 less than the larger number. What are the numbers? Larger number = Smaller number = 3. Two mechanics worked on a car. The first mechanic worked for 15hours, and the second mechanic worked for 5hours. Together they charged a total of $1725. What was the rate charged per hour by each mechanic if the sum of the two rates was $175per hour? First mechanic per hour = $ Second mechanic per hour = $ 5. Solve the compound inequality. 6<3x + 3<18 <---------------------------|-----------------------------> Graph the solution on the number line. 6. Solve the compound inequality. 2y+3 or 3y-39 7 write the solution in interval notation 7. Use substitution to solve the system. x= 3y - 13 5x + 2y = 26 X= y= 8. Two systems of equations are given below. For each system, choose the best description of its solution. If applicable, give the solution. -x-2y=-2 X+2y=2 -x-3y=6 X+3y=6 9. The sets B and C are defined as follows. B = {
