Answer:

The sentence that represents the inequality "-2b + 7 > 27.5" is "negative two times a number plus seven is greater than twenty-seven and five tenths"

Explanation:

The goal of this exercise is to translate the inequality (in math language) to a colloquial statement.

Let's do the translation part by part.

The expression "2b" can be translated to "two times a number".

Then, the expression "-2b" can be translated to "negative two times a number".

The expression "-2b + 7", as we are adding 7 to the previous expression, can be translated to "negative two times a number plus 7".

The expression "-2b + 7 > ...", means that the expression at the left of the inequality is greater than the one at the right. Then, it can be translated as "negative two times a number plus 7 is greater than ...".

Finally, the expression "-2b + 7 > 27.5", can be translated as "negative two times a number plus seven is greater than twenty-seven and five tenths"
