e)6/7=x/21​

Answer 1

Resposta: A) 2

B) 15

C) 1

D) 28

E) 18

Explicação passo a passo:

A) 8/x= 50/25 simplifica o 50 e o 25 por 25

8/x= 2 => x=8/4= 2

B) -11/55=3/x simplifica o -11/55 dividindo por 11

-1/5=3/x => -x=15 .(-1) => x= 15

C) 18/8+x=2/x => 2(8+x)=18x => 16 +2x= 18X => x= 1

D)  1/4=7/x => x=28

E) 6/7= x/21 =>  7x=21.6 => x= 18
