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:
B. [tex]?+8=19[/tex]
D. [tex]11+x=19[/tex]
Step-by-step 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.
