The half-life of a certain type of soft drink is 5 hours. If you drink 50mL of this drink, the formula y 50(0.5)t/5 tells the amount of the drink left in your system
after t hours. How much of the soft drink will be left in your system after 16 hours?
Round to the nearest hundredth.

What is the solution to this system of equations? y= 2x - 3.5 x - 2y = -14

Delbert keeps track of total of the total number of points he earns on homework assignments, each of which is worth 60 points. at the end of the semester he has 810 points. write an equation for delbert’s average homework score a in terms of the number of assignments n.

Which of these statements is correct? the system of linear equations 6x - 5y = 8 and 12x - 10y = 16 has no solution. the system of linear equations 7x + 2y = 6 and 14x + 4y = 16 has an infinite number of solutions. the system of linear equations 8x - 3y = 10 and 16x - 6y = 22 has no solution. the system of linear equations 9x + 6y = 14 and 18x + 12y = 26 has an infinite number of solutions.
