Answer 1

Resposta:

D = -120

E = -17

F = 98

G = -12

Explicação passo a passo:

D) $-109+5(-8)-(-29)$

Calculando:

$-109-40+29$

$-149+29$

$-120$

E) $21:(3-10)+2(66:11-13)$

Calculando:

$21:(-7)+2(6-13)$

$21:(-7)+2(-7)$

$-3-14$

$-17$

F) $-23-[-4-5+3(2-4)-81-(25)]$

Calculando:

$-23-[-4-5+3(-2)-81-(25)]$

$-23-[-4-5-6-81-(25)]$

$-23-[-15-81-(25)]$

$-23-[-121]$

$-23+121$

$98$

G) 5+3(-8)-{56:[-4-4]-2[10+(-5-5)]}

Calculando:

5+3(-8)-{56:[-4-4]-2[10+(-10)]}

5+3(-8)-{56:[-4-4]-2[0]}

5+3(-8)-{56:[-4-4]}

5+3(-8)-{56:[-8]}

5+3(-8)-{-7}

5+3(-8)+7

5+(-24)+7

5-24+7

-19+7

-12
