To evaluate the expression \(10(3w - 2y)\) when \(w = 2\) and \(y = 5\), follow these steps:
- Substitute the values of \(w\) and \(y\) into the expression:
\[ 10(3(2) - 2(5)) \]
- Calculate the values inside the parentheses:
\[ 3(2) = 6 \] \[ 2(5) = 10 \]
- Now substitute these values back into the expression:
\[ 10(6 - 10) \]
- Calculate the subtraction:
\[ 6 - 10 = -4 \]
- Now multiply by 10:
\[ 10(-4) = -40 \]
Thus, the result of the expression is \(-40\).
The correct response is \(-40\).
