Answer 1

Resposta e explicação passo-a-passo:

A (6 x 3 + 7) + ( 4 x 8 -7)=

(6 x 3 + 7) + ( 4 x 8 -7)

(18 + 7) + ( 4 x 8 -7)

(18 + 7) + ( 4 x 8 -7)

(18 + 7) + ( 32 - 7)

25 + ( 32 - 7)

25 + 25

B (5 + 5 x 5)+ ( 5 x 5 +5)=

(5 + 5 x 5)+ ( 5 x 5 +5)

(5 + 25)+ ( 5 x 5 +5)

(5 + 25)+ ( 25 +5)

30 + ( 25 +5)

30 + 30

C (3 + 33 : 3) x (12: 3 + 1) =

(3 + 33 : 3) x (12: 3 + 1)

(3 + 11) x (12: 3 + 1)

(3 + 11) x (4 + 1)

14 x (4 + 1)

14 x 5

D 20- (8 x 2 + 4) : (15 :5 +1 ) =

20- (8 x 2 + 4) : (15 :5 +1 )

20- (16 + 4) : (15 :5 +1 )

20- (16 + 4) : (3 +1 )

20- 20 : (3 +1 )

20- 20 : 4

20- 5

E 10 +(7 x 7 + 11):(3 x 9 +3)=

10 +(7 x 7 + 11):(3 x 9 +3)

10 +(49 + 11):(3 x 9 +3)

10 +(49 + 11):(27 +3)

10 +(60):(27 +3)

10 +(60):(30)

10 +2
