Translate this phrase into an algebraic expression. 15 more than twice a number Use the variable \( n \) to represent the unknown number. \( \square \)

The phrase "15 more than twice a number" can be translated into an algebraic expression as \( 2n + 15 \). Here, \( 2n \) represents twice the number \( n \), and adding 15 gives you the final expression. To further clarify, algebraic expressions serve as a bridge between words and mathematics, helping us quantify and solve real-life problems. For instance, if \( n \) were to represent the age of a person, \( 2n + 15 \) could represent the combined age of that person at two years younger than they are currently plus 15 years!
