Question

these shoes was ou were Very expensive​

Answer 1

this shoe was very expensive

Answer 2

Resposta:

were

Explicação:

Você só precisa levar pelo raciocínio dos sujeitos e do verbo to be.

I - He - She - it = was

You - we - They = were

These shoes, se for deixar subentendido, o sujeito na frase ficaria:

They were very expensive (eles foram muito caros), logo chegamos a conclusão que neste caso, o mais adequado é usar were.
