Question

Write an algebraic expression for the word expression.

Answer 1

Answer:

9+x

Step-by-step explanation:

It is an expression so it doesn't need an equal sign. Sum means adding, so you add nine and x, which represents a number.

Answer 2

Answer: 9 + x

The word "sum" indicated that we are adding the two numbers, so we put the number and the variable in an expression that adds them together. There is no indication that there is anything else we need to add to this expression, so this is all you need. (The "x" is a variable, which can represent any number.)
