Question

Resolva as expressões numéricas. a) -16 + {-10 + [(82 – 12) + (44 + 12)] – 26} b) {[(5 · 4 + 22) ÷ 7 + (3 + 155 ÷ 5) · 3] · 2 – (19 – 7) ÷ 6} · 2 + 12

Answer 1

Explicação passo-a-passo:

a)-16+{-10+[(82-12)+(44+12)]-26}=

-16+{-10+[(70)+(56)]-26}=

-16+{-10+[126]-26}=

-16+{-10+126-26}=

-16+{-10+100}=

-16+{90}=

-16+90=

84

b){[(5*4+22)÷7+(3+155÷5)*3]*2-(19-7)÷6}*2+12=

{[(20+22)÷7+(158÷5)*3]*2-(12)÷6}*2+12=

{[42÷7+31,6*3]*2-12÷6}*2+12=

{[6+94,8]*2-12÷6}*2+12=

{100,8*2-12÷6}*2+12=

201,6-2*2+12=

199,6*2+12=

399,2+12=

411,2
