Answer 1

Resposta:

a) = 4

b) = -14

c) = 2.8

d) = 35

e) = 61

Explicação passo-a-passo:

a) 1x(1+7)-16:(1+3)

1x8-16:4

8-4

4

---------------

b) 2x(7+1) - 32 : (7+9)=

2 x (8) - 32 : (16)

2 x (8) - 2  

16 - 2 = -1

-------------------

c) 3×(6+3)-10÷(2+8)

3×9-10÷(2-8)

27-10÷6

17÷6= 2.8

-----------------------

d) 9x(1+3)-15÷(9+6)

9x 4 - 15 ÷ 15

36 - 1
