in the summer Sue swims every six days lifts every four days and runs every 16 days and she did all these activities today and how many days will she do all three activities again on the same day

1. a parachutist is 800 feet above the ground when she opens her parachute. she then falls at a constant rate of 5 feet per second. select the equation that represents this situation. h = -800t + 5 y = -5x + 800 h = 5t - 800 y = 800x + 5 i need

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

Last one and the bottom answer choice is y=(x-4)^2+1 you guys!
