Questão 27:


Usando números inteiros positivos ou negativos e considerando o térreo como origem , indique o andar onde o elevador se encontra quando sobre 1 andar e desce 3 andares .


a) + 1

b) 0

c) – 1

d) 2



Marque a única resposta antelativa correta sobre as expressões envolvendo número inteiros .


a) (-12 ) : (+12) = + 1

b) (-5) . (-7) = + 35

c) (10) . (-5) = 50

d) (-12) : (-3) = + 5


Aplicando os conceitos de números simétricos (opostos) e valor absoluto ( módulo ) . Maque a única resposta correta :


a) + 7 e -7 são números semelhantes

b) O módulo de 82 e 83

c) 12 é módulo de + 12 e de – 12

d) O posto de -6 é - 3

Resposta:

Nessa questão 27 na verdade são 3 perguntas, dividi em partes, dê uma olhada no passo-a-passo.

Explicação passo-a-passo:

Parte 1:

Como o térreo é a origem, então, ele é o andar zero.

Subiu um andar 0+1 = 1ª andar

Desce três andares = 1 - 3 = -2 (ele está no 2ª andar subterrâneo)

PS: Dê uma conferida se a pergunta está certa ou se falta informação.

Parte 2: Sobre a questão com números inteiros, só a letra "b" que tem: (-5) . (-7) = + 35 está correta.

Parte 3:  Só a letra "c" está correta, 12 é módulo de + 12 e de – 12.
