Question

aplique a propriedade distributiva nas expressões;

-5.(-3+6-10)=

(-10+30)/5=

(2+1)/3=
5 3 4

Answer 1

-5.(-3+6-10)= 
(-5 .(-3) + (-5.6) +(-5.(10) =
 +15 + (-30) -(-50) =
   15 - 30 + 50 = 35

(-10+30)/5=
(-10:5)+(30:5) = -2 + 6 = 4

(2/5+1/3) : 3/4 =
(2/5:3/4) + (1/3:3/4) = 
(2/5*4/3) + (1/3*4/3)=
  8/15 + 4/9 =  ---mmc(9,15) = 45
  24/45 + 20/45 = 
  44/45
