Problem 38 - Algebra 1: Concepts and Skills

Question

Evaluate the expression. $$ 8.4-5.2-(-4.7) $$

Step-by-Step Solution

Answer

The result of the evaluated expression is 7.9.

Step 1: Understand the Problem

The problem at hand is \(8.4-5.2-(-4.7)\). This involves performing subtraction and addressing a negative value within brackets.

Step 2: Subtraction of First Two Values

Start by subtracting the first two values. When 5.2 is subtracted from 8.4, the answer is 3.2. So, \(8.4 - 5.2 = 3.2\).

Step 3: Handling Negative Value

The next operation is subtracting -4.7. Remember that subtracting a negative value is the same as adding a positive value. So, \(3.2 - (-4.7) = 3.2 + 4.7\).

Step 4: Perform Addition

Finally, add the two values from the previous step. When 4.7 is added to 3.2, the result is 7.9. So, \(3.2 + 4.7 = 7.9\).
