D)35.(7-5)=

E)(7.9-3):5=

F)35:(4.3-5)=

G)3.(15-5)=

Answer 1

Resposta:

Explicação passo-a-passo:

A) (6 + 2) . 0,3 + 5

(6 + 2) . 0,3 = 2,4 + 5= 7,4

B)$\frac{4,7 +12}{3,5+5} = \frac{16,7}{8,8}=1,96$

C) 7,2+10-50:10   |    50:10 = 5

    7,3+10-5= 12.2

D)35 . (7 - 5) = 35 . 2 = 70

E) $\frac{7,9-3}{5} = \frac{4,9}{5}= 0.98$

F)  $\frac{x}{-y} = -\frac{x}{y}$

 $\frac{35}{4,3-5} = \frac{35}{-0.7} = -\frac{35}{0,7}= - 50$

G)3 . (15 - 5) = 3 . 10 = 30
