Ascience test, which is worth 100 points, consists of 24 questions. Each question is worth either 3 points or 5 points. If x is the
number of 3-point questions and y is the number of 5-point questions, the system shown represents this situation.
x+y = 24
3x + 5y = 100
What does the solution of this system indicate about the questions on the test?

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212
