麻烦给出解题步骤,万分感谢!
1. Butch can assemble 6 patio tables per hour. Jose can assemble 4 patio
tables per hour. How many hours will it take them working together to
assemble 60 tables?
2. How many 5% maple syrup and water mixture must be added to 100% pure
maple syrup to produce 5 quarters of syrup that is 10% maple syrup?
3. Oscar wants to fill a pond that irrigates his crops. One water source
fills the pond.1.5 times faster than a second source. When both sources are
used together, the pond is filled in 6 hours. Which equation describes how
fast both sources can fill the pond together?
1/r+2/3r=1/6
1/r-3/2r=1/6
6=1.5r+r
6=r + ½ r
