You go christmas shopping at the mall. you buy a sweater for your mom for $22.99, a book for your dad for $12.75, and toy cars for your cousins that cost $4.50 each. write and simplify an algebraic expression to represent your purchases. (let x = the amount of toy cars.)

Two language majors, anna and megan, took exams in two languages. anna scored 85 on both exams. megan scored 74 on the first exam and 85 on the second exam. overall, student scores on the first exam had a mean of 82 and a standard deviation of 4, and the second exam scores had a mean of 71 and a standard deviation of 13. a) to qualify for language honors, a major must maintain at least an 85 average across all language courses taken. so far, which of anna and megan qualify? b) which student's overall performance was better?

Solve for x and y: 217x + 131y = 913; 131x + 217y = 827
