1. 

The developers of a web site are tracking its number of adult users and teenage users. They found that the equation 62x + y = 675 models the number of teenage users over time, and the equation 189x - 2y = -164 models the number of adult users over time. In both equations, x is the number of years since 2000, and y is the number of users in thousands. During what year was the number of teenage users and adult users the same?

Find the lengths of the two pieces of cord. shorter piece cm Tutorial longer piece cmThe employees at a bank ordered 4 turkey sandwiches and 2 salads from a local deli. The total cost for the order was $25. If a salad costs $1 less than a turkey sandwich, what is the cost of a turkey sandwich and the cost of a salad? turkey sandwich $ salad TutorialGranola costs $4.50 per pound. Assorted nuts cost $7 per pound. How many pounds of granola and nuts are needed to make 7 pounds of trail mix that costs $5 per pound? granola pounds assorted nuts pounds TutorialSolve the system using substitution. (If the system has infinitely many solutions, express your answer in terms of t such that x = t. If there is no solution, enter NO SOLUTION.) Xty =9 2x + 2y = 18 (x, y ) = Tutorial x Did you solve the first equation for one of the variables? Did you substitute your result into the second equation and solve for the other variable?Solve the equation using the elimination method. Give the answer in the form of an ordered pair in terms of x. Note that the method of elimination may be referred to as the addition method. 4 x + Y = ( x, V ) = Tutorial Did you notice that a coefficient for one variable in one of the equations is a multiple of the coefficient for the same variable in the other equation? Multiply only one of the equations by a constant, an in terms of x for the solution in the form of an ordered pair
