Question - Calculation of a Linear Combination

The given expression is a linear combination of numbers:

To solve the expression, perform the operations as indicated:

\( 3(0.6) + 3(7) - 6 \left( \frac{2}{3} \right) \)

First, multiply each term inside the parentheses:

\( 3 \times 0.6 = 1.8 \)

\( 3 \times 7 = 21 \)

\( 6 \times \frac{2}{3} = 4 \)

Combine the results of the multiplications:

\( 1.8 + 21 - 4 \)

Now, add and subtract the numbers:

\( 1.8 + 21 = 22.8 \)

\( 22.8 - 4 = 18.8 \)

So the solution to the expression is:

\( 18.8 \)
