It takes 7 gardeners 8 hours to plant 1 680 seedlings on a piece of land. Calculate (in hours and minutes) how long it would take 12 gardeners to

plant the seedlings​

Solve 3x-18=2y and 5x-6y=14 by elimination or substitution . show all !

How do i start to solve? would appreciate a walk-thru! a bird sitting 16ft above the ground in an apple tree dislodges an apple. after how many seconds does the apple land on the ground? (assuming that no branches will interfere with it's fall)

Someone answer asap for ! 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
