Question

The expression is to be rewritten by applying the commutative and associative properties of addition. If you use each property only one time, which expression could be the result

Answer 1

Let's begin by listing out the given information:

`\begin{gathered} 7.3+(2+(-3.1)) \\ The\text{ }commutative\text{ }property\text{ }of\text{ }addition\text{ i}s\text{ shown below:} \\ a+b=b+a \\ \Rightarrow(-3.1)+2)+7.3 \\ The\text{ }associative\text{ }property\text{ }of\text{ }addition\text{ i}s\text{ shown below:} \\ \mleft(a+b\mright)+c=a+\mleft(b+c\mright) \\ (-3.1)+2)+7.3=7.3+(-3.1)+2) \\ \\ \therefore7.3+(-3.1)+2) \end{gathered}`

Therefore, the answer is: 7.3 + (-3.1) + 2)
