Question

Explain why 15 + ½n is an algebraic expression.

Answer 1

Answer:

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

Why do we have math if we can describe things in words? Algebraic expressions are useful because they represent the value of an expression for all of the values a ... 2n + n = 16 - 1 - Simplify. 3n = 15 - Divide both sides by 3. n = 5 <-- answer!
