In 1989, dutch ice skater dries van wijhe skated 200 km at an average speed of 35.27 km/h. how long was he skating? use the formula d = rt, where d is the distance in km, r is the rate in km/h, and t is the time in hours.

John used linear combination to solve the system of equations shown. he did so by multiplying the first equation by -3 and the second equation by another number to eliminate the x-terms. what number did jonas multiply the second equation by? 4x-6y=23x+5y=11

Which expression is equivalent to 16 in exponential form? a) 4 × 4 b) 8 × 2 c) 23 d) 24

10x − 5y + 14 = 0 whats the answer pls
