Question

evaluate the expression when w = 2 and y = 5

10 (3w - 2y)

Answer 1

To evaluate the expression \(10(3w - 2y)\) when \(w = 2\) and \(y = 5\), you can follow these steps:

1. Substitute \(w\) and \(y\) into the expression:

\[
10(3(2) - 2(5))
\]

2. Calculate the products inside the parentheses:

\[
3(2) = 6 \quad \text{and} \quad 2(5) = 10
\]

3. Now substitute these values back into the expression:

\[
10(6 - 10)
\]

4. Perform the subtraction inside the parentheses:

\[
6 - 10 = -4
\]

5. Finally, multiply by 10:

\[
10(-4) = -40
\]

So, the value of the expression \(10(3w - 2y)\) when \(w = 2\) and \(y = 5\) is \(-40\).
