What is 12 more than a number?
then “12 more than a number” for us means 12 more than N. And in math “more than” usually means you are adding. So 12 more than N would be 12 + N.
How do you write 5 more than a number?
A number 5 more than this number is the number obtained after adding 5 to the given number. So a number 5 more than x is equal to x+5. Hence “5 more than a number” written as an algebraic expression is “x+5”. So, the correct answer is “x+5”.
What is the algebraic expression for a number?
An algebraic expression is an expression involving numbers, parentheses, operation signs and pronumerals that becomes a number when numbers are substituted for the pronumerals. For example 2x + 5 is an expression but +) × is not. 3x + 1 = 3 × 2 + 1 = 7 and 5(x2 + 3x) = 5(22 + 3 × 2) = 30.
How do you write 8 more than a number?
Explanation: The words “more than” in mathematical terms refer to the process of addition. In this case, we need to have 8 more than x , or x+8 . Hence, the answer, x+8 .

How do you write three times a number?
Three times a number is represented by 3n . Plus 8 is obvious. “Is” is equivalent to writing “equals”.
How do you write twice a number?
