Question

if 597 y8 is divisible by 9 y is a digit find the value of y
​

Answer 1

$\frac{597 {y}^{8} }{9y} = 64.33 {y}^{7}$

Answer 2

Answer:

Modal verbs determine the mood of the sentence, like obligation, permission, possibility, necessity and so on. In the given sentence, "could" is used to indicate a polite request made by the speaker, if the listener could pass the salt. Hence it's a modal verb and option A is correct. "You" is a pronoun that refers to the listener, it does not determine the mood of the sentence. "Pass" is a verb that refers the action of transferring something, the salt here. "Salt" is a noun and refers to a condiment used in food. None of these determine the mood of the sentence, hence they're not modal verbs and options B, C and D are incorrect.
