To determine which of the given math statements contain variable(s), let's analyze each statement step by step:
Statement A:
[tex]\[ 5-5=0 \][/tex]
This statement is a basic arithmetic equation involving fixed numbers only. There are no variables present. Therefore, Statement A does not contain any variables.
Statement B:
[tex]\[ 11+x=19 \][/tex]
In this statement, there is a term "x" which is a variable. Variables are symbols that represent unknown values. Therefore, Statement B does contain a variable.
Statement C:
[tex]\[ 34-6=28 \][/tex]
This is another arithmetic equation with only constants and no variable terms. Therefore, Statement C does not contain any variables.
Statement D:
[tex]\[ ?+8=19 \][/tex]
In this statement, the symbol "?" represents an unknown value, which serves the same purpose as a variable. Therefore, Statement D does contain a variable.
Based on the above analysis, the results are as follows:
- Statement A does not contain a variable.
- Statement B does contain a variable.
- Statement C does not contain a variable.
- Statement D does contain a variable.
Hence:
- Statement A: No variable
- Statement B: Contains variable
- Statement C: No variable
- Statement D: Contains variable
The final results are:
- Statement A: [tex]\(\boxed{\text{False}}\)[/tex]
- Statement B: [tex]\(\boxed{\text{True}}\)[/tex]
- Statement C: [tex]\(\boxed{\text{False}}\)[/tex]
- Statement D: [tex]\(\boxed{\text{True}}\)[/tex]
