Question

c) 15+[(3×6-2) - (10 - 6:2)]

d) 50 - {40 - 3 × [5 - ( 10 - 7)]}

​

Answer 1

Explicação passo-a-passo:

c)15+[(3×6-2)-(10-6÷2)]=

15 +[(18-2)-(10-3)]=

15+ [(16)-(7)]=

15 +[16-7]=

15+ 9=

24

d)50-{40-3×[5-(10-7)}=

50 - {40-3×[5- 3]}=

50-{40-3 × 2}=

50-{40-6}=

50 - {34}=

50-34=

16
