Find three consecutive numbers such that the sum of one-fourth the first and one-fifth the second is five less than one-seventh the third

Match each inequality to the number line that represents its solution

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′.
