Answer: The correct option is (C) 9y + 13.
Step-by-step explanation: We are given to select the expression that represents the following statement :
“nine times a number plus thirteen”
Let the number be represented by y.
Then, nine times the number is written as follows :
[tex]9\times y=9y.[/tex]
Since we are to add 13, so the final expression is given by
[tex]E=9y+13.[/tex]
Thus, the required expression is [tex]9y+13.[/tex]
Option (C) is CORRECT.
