The correct Answer is:
To evaluate the expression \((9|3-5|-5|4| + 10)/(-3(5) - 2 \times 4 + 2)\), we will follow these steps: ### Step 1: Simplify the absolute values First, we need to evaluate the absolute values in the expression. - Calculate \(3 - 5 = -2\), so \(|3 - 5| = 2\). - Calculate \(|4| = 4\) (since 4 is already positive). Now we can rewrite the expression: \[ (9 \cdot 2 - 5 \cdot 4 + 10) \] ### Step 2: Substitute the absolute values into the expression Substituting the values we calculated, we have: \[ (9 \cdot 2 - 5 \cdot 4 + 10) = (18 - 20 + 10) \] ### Step 3: Simplify the numerator Now, simplify the numerator: \[ 18 - 20 + 10 = 18 - 20 = -2 \quad \text{and} \quad -2 + 10 = 8 \] So, the numerator is \(8\). ### Step 4: Simplify the denominator Now, we will simplify the denominator: \[ -3(5) - 2 \times 4 + 2 \] Calculating each term: - \(-3 \cdot 5 = -15\) - \(-2 \cdot 4 = -8\) Now substituting these values into the denominator: \[ -15 - 8 + 2 = -15 - 8 = -23 \quad \text{and} \quad -23 + 2 = -21 \] So, the denominator is \(-21\). ### Step 5: Combine the results Now we can combine the results from the numerator and denominator: \[ \frac{8}{-21} = -\frac{8}{21} \] ### Final Answer Thus, the final answer is: \[ -\frac{8}{21} \] ---
