Sarah is 76, Margaret is 38, Jenny is 19.

S + M + J = 133

S + 1/2S + 1/4 S = 133

7/4 S = 133

Is Sarah a concrete noun?

Yes, "Sarah" is a concrete noun because it refers to a specific person. Concrete nouns are names of things that can be perceived through the five senses, and since Sarah is a tangible individual who can be seen and interacted with, she fits this definition.

Which is correct Sarah is beeter than me or Sarah is better than I?

"Sarah is better than I" is the traditional answer (even aside from the misspelling of "beeter"). The reason is that, by convention, "than" when following a predicate adjective in the comparative form is normally supposed to be interpreted as subordinate conjunction that begins an adverbial clause of the form, "than {explicitly stated subject} {implicit form of the verb 'to be' appropriate to the stated subject} {basic form the adjective that, in its comparative form, precedes 'than'}", where each phrase between curly brackets defines an explicitly stated or implicit word as indicated. Thus, the sentence given is to be understood, with the implicit words between square brackets, as "Sarah is better than I [am good]" However, note that the above rule is not necessarily followed when the verb in the independent clause of the sentence is a transitive verb and the comparative adjective follows an object of that verb rather than a predicate adjective, as in the example sentence. In that instance, there are two different possibilities: "My mother likes my sister better than I" means that my mother likes my sister better than I like my sister, but "My mother likes my sister better than me" means that my mother likes my sister better than my mother likes me.


Write a word problem that can be evaluated by algebraic expression y - 95 and evaluate it for y equals 125?

Sure! Here is a word problem that can be represented by the algebraic expression y - 95: "Sarah had y dollars in her savings account. She spent $95 on a new dress. Write an expression to represent how much money she has left in her account." If y equals 125, we can evaluate the expression y - 95 by substituting y with 125: 125 - 95 = 30 Therefore, Sarah has $30 left in her savings account after buying the dress.
