Let the number be x and so the expression is 8x
It could be: -3/8+4x-9z as an algebraic expression
Write the following as an algebraic expression using x as the variable: The sum of a number and -8
x+(-8)This simplifies to x-8
Write the following as an algebraic expression using x as the variable: The sum of a number and -8
The sum of fifteen times a number and eight.
Watch closely:The sum of 'n' and '8' is written as (n + 8).
As an algebraic expression it is simply: 8+q
4*(x - 8)
x/8
