The order in which two numbers are added does not change their sum.
Name the property that is illustrated by the statement below:
`2\ +\ \left(7\ +\ 3\right)\ =\ \left(2\ +\ 7\right)\ +\ 3`
`2\ +\ \left(7\ +\ 3\right)\ =\ \left(2\ +\ 7\right)\ +\ 3`
The property that is illustrated by the statement is the associative property of addition.

Evaluate the expression Show your work below:
ion `3b-ac` when `a\ =\ -2`, `b\ =3`, and `c=0.5`.
ion `3b-ac` when `a\ =\ -2`, `b\ =3`, and `c=0.5`.
To evaluate the expression `3b - ac` when `a = -2`, `b = 3`, and `c = 0.5`, we substitute the values of `a`, `b`, and `c` into the expression:
`3b - ac = 3(3) - (-2)(0.5)`
Next, we simplify the expression:
`3b - ac = 9 - (-1)`
`3b - ac = 9 + 1`
`3b - ac = 10`
Therefore, when `a = -2`, `b = 3`, and `c = 0.5`, the expression `3b - ac` evaluates to 10.
`3b - ac = 3(3) - (-2)(0.5)`
Next, we simplify the expression:
`3b - ac = 9 - (-1)`
`3b - ac = 9 + 1`
`3b - ac = 10`
Therefore, when `a = -2`, `b = 3`, and `c = 0.5`, the expression `3b - ac` evaluates to 10.
