Question

Which of the following math statements contain variable(s)? Check all that apply A. 5-5=0 B. ?+8=19 C. 34-6=28 D. 11+x=19

Answer 1

A variable is a letter in the equation.

A, B, and C dont have variables... unless a question mark is considered a variable at your school (I dont consider it a variable).

D has an x in the equation, so D has a variable.

Answer 2

B.
`?+8=19`

D.
`11+x=19`

Explanation:

We are asked to choose the math statements that contain variable.

We know that a variable is a quantity that is not fixed or consistent. We can substitute any value in place of a variable.

A variable can be a letter or a symbol.

Upon looking at our given choices, we can see that options B and D are correct choices.

In option B, we have a symbol variable that is ?, therefore, option B is correct choice.

In option D, we have a letter variable that is x, therefore, option D is correct choice.
