Answer 1

Explicação passo-a-passo:

1) calcule o valor das expressões

a) 60 - (14-4+6)-16-6=

60-(10+6)-16-6=

60-(16)-22=

44-22=

22

b) 2-{8+ [3x (8-5)-1]-16} =

2-{8+[3.(3)-1]-16}=

2-{8+[9-1]-16}=

2-{8+[8]-16}=

2-{16-16}=

2-0=

2

c) 30: (4+ [16-(3+7)-1]+2}=

30:4+[16-(10)-1]+2}=

30:4+[6-1]+2}=

30:4+[5]+2=

7,5+7=

14,5
