B) 2.(12+9.7)-105 =

Answer 1

Resposta:

Is the point a multiplication?

A) (7+4.10).(60-8.7)-(11+2.5) =

=(7+40)(60−(8)(7))−(11+(2)(5))

=47(60−(8)(7))−(11+(2)(5))

=47(60−56)−(11+(2)(5))

=(47)(4)−(11+(2)(5))

=188−(11+(2)(5))

=188−(11+10)

=188−21

=167

B) 2.(12+9.7)-105 =

=2(12+63)−105

=(2)(75)−105

=150−105

=45
