Answer 2

Resposta:

34

Explicação passo-a-passo:

Primeiro passo:

Realize as divisões e multiplicações.

240 / 10 + 2 x [20-45 / (13-2x5)]

= 24 + 2 x [20 - 45 / (13 * 10)]

Segundo Passo:

Resolva o parenteses.

= 24 + 2 x [20 - 45 / 3]

Terceiro Passo:

Resolva o colchete

= 24 + 2 x [20 - 15]

= 24 + 2 * 5

Por fim, juntar a fazer as contas

24 + 2 * 5

= 24 + 10

Totalizando = 34
