The correct Answer is:
To solve the problem of dividing 180 into two parts where the second part is 12 more than twice the first part, we can follow these steps: ### Step 1: Define the Variables Let the first part be \( x \). Then, according to the problem, the second part can be expressed as \( 12 + 2x \). ### Step 2: Set Up the Equation Since the total of the two parts is 180, we can write the equation: \[ x + (12 + 2x) = 180 \] ### Step 3: Simplify the Equation Combine like terms: \[ x + 12 + 2x = 180 \] This simplifies to: \[ 3x + 12 = 180 \] ### Step 4: Isolate the Variable Subtract 12 from both sides to isolate the term with \( x \): \[ 3x = 180 - 12 \] \[ 3x = 168 \] ### Step 5: Solve for \( x \) Now, divide both sides by 3 to find \( x \): \[ x = \frac{168}{3} \] \[ x = 56 \] ### Step 6: Find the Second Part Now that we have the first part, we can find the second part using the expression we defined earlier: \[ \text{Second part} = 12 + 2x = 12 + 2(56) \] Calculating this gives: \[ = 12 + 112 = 124 \] ### Conclusion Thus, the two parts are: - First part: \( 56 \) - Second part: \( 124 \) ### Final Answer The two parts are 56 and 124. ---
