Question

1. Calculé +12-4[8(-3-1) / (-2)+(-7)]
2. Calculé -30{(12-15)(-6)+(18-13)(-8)-[(12-16)]}
3. Calculé (-2-11)4+3[(-6)/(-3)]-18/(10-1)
4. Reduzca P= (-40)/(-4)+(-30)/(+6)-(-24)/(-4)
5. Reduzca P= (-40)/(-4)+(-30)/(+6)-(-24)/(-4)
Lo necesito urgente:c

Answer 1

1.
$12-4[8(-3-1)/(-2)+(-7)]$

$12-4[8(-4)/(-2)+(-7)]$

$12-4[-32/(-2)+(-7)]$

$12-4[16+(-7)]$

$12-4[16-7]$

$12-4[9]$

$12-36$

$-24$



2.
$-30{(12-15)(-6)+(18-13)(-8)-[(12-16)]}$

$-30{(-3)(-6)+(5)(-8)-[-4]}$

$-30{18+(-40)+4}$

$-30{-18}$

$-48$


3.

$(-2-11)4+3[(-6)/(-3)]-18/(10-1)$

$(-13)4+3[2]-18/(9)$

$(-52)+(6)-(2)$

$-48$



4.

$P= (-40)/(-4)+(-30)/(+6)-(-24)/(-4)$

$P= (10)+(-5)-(6)$

$P= -1$



5.

$P= (-40)/(-4)+(-30)/(+6)-(-24)/(-4)$

$P= (10)+(-5)-(6)$

$P= -1$
