The distance formula states that distance (d) is equal to the product of rate (r) and time (f). given this problem: john at a constant rate of 200 m per minute. how many minutes did it take john to run 500 m? which equation could be used to solve the problem. a. t = 500d/200b. t = 200/500c. t = 500/200d. t = 200r/500

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.
