Sure, here is a detailed answer to your question:

The construction "there is / are" is used to talk about the existence or presence of something. "There is" is used when we talk about a singular noun, while "there are" is used when we talk about plural nouns.

To write sentences using "there are" with the given numbers expressed in words, we need to choose the right forms of "is" or "are" based on whether the noun that follows is singular or plural.

Let's go through each number one by one:

1. Seven - Since the number 7 is more than one, we use "There are."
Example sentence: There are seven days in a week.

2. Nine - Again, since the number 9 is more than one, we use "There are."
Example sentence: There are nine planets in our solar system.

3. Fifteen - Like the previous examples, since the number 15 is more than one, we use "There are."
Example sentence: There are fifteen students in my class.

4. Twenty-six - Similar to the previous examples, since the number 26 is more than one, we use "There are."
Example sentence: There are twenty-six letters in the English alphabet.

5. Thirty - Again, since the number 30 is more than one, we use "There are."
Example sentence: There are thirty days in the month of June.

6. Fifty - Like the previous examples, since the number 50 is more than one, we use "There are."
Example sentence: There are fifty states in the United States of America.

In summary, when writing sentences using "There are" with the given numbers expressed in words, we use "are" because all the numbers are more than one. By following this rule, we have constructed sentences that clearly convey the existence or presence of the things represented by those numbers.
