20 someone me create a real world problem with an equation to solve it? for my algebra class.

X+ y = 5 ; x - y =3 solve using linear combination

Choose the more precise measurement. 26.4 cm or 8.39 cm

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′.
