Kopy kwik has 2 copiers. one can produce a year end report in 20 min. the other can produce the same document in 30 min. how long would it take both machines, working together, to produce the report?

Type the correct answer in each box. spell all words correctly. a sequence of transformations maps ∆abc onto ∆a″b″c″. the type of transformation that maps ∆abc onto ∆a′b′c′ is a . when ∆a′b′c′ is reflected across the line x = -2 to form ∆a″b″c″, vertex of ∆a″b″c″ will have the same coordinates as b′.
