Question

7. Resolva as equações

A) -3w=18

B) k + 12=20

C) m + 15= 11

D) 5v + 1= 36

E) 4t - 14= 22

Answer 1

Resposta:

A) -6 B) 8 C) -4 D) 7 E) 9

Explicação passo a passo:

A) -3w = 18 >>> (multiplica tudo por -1) >>> 3w = -18 >>> w = -18/3 >>> w = -6

B) k + 12 = 20 >>> k = 20 - 12 >>> k = 8

C) m + 15 = 11 >>> m = 11 - 15 >>> m = -4

D) 5v + 1 = 36 >>> 5v = 36 -1 >>> 5v = 35 >>> v = 35/5 >>> v = 7

E) 4t - 14 = 22 >>> 4t = 22 + 14 >>> 4t = 36 >>> t = 36/4 >>> t = 9
