Question

Evaluate the expression. $$16.9-1.5(1.8+0.2)$$

Short answer

The evaluated expression is \(13.9\).

Step-by-step solution

Solve the expression inside the brackets

Add the values \(1.8 + 0.2\) together, which makes \(2.0\). Now, the expression becomes \(16.9 -1.5(2.0)\).

Perform the multiplication

Next, multiply \(1.5\) with \(2.0\) to get \(3.0\). Substitute this into the equation so it becomes \(16.9 - 3.0\).

Perform the subtraction

Finally, subtract \(3.0\) from \(16.9\) to get \(13.9\).
