The correct Answer is:
To solve the inequality \( \frac{2(4k+1)}{3} \geq \frac{k(6+5)-3}{2} \), we will follow these steps: ### Step 1: Eliminate the fractions To eliminate the fractions, we will multiply both sides of the inequality by the least common multiple (LCM) of the denominators, which is 6. \[ 6 \cdot \frac{2(4k+1)}{3} \geq 6 \cdot \frac{k(6+5)-3}{2} \] ### Step 2: Simplify both sides Now, simplify both sides: - Left side: \[ 6 \cdot \frac{2(4k+1)}{3} = 2 \cdot 2(4k+1) = 4(4k+1) = 16k + 4 \] - Right side: \[ 6 \cdot \frac{k(6+5)-3}{2} = 3(k(11)-3) = 3(11k - 3) = 33k - 9 \] So the inequality now looks like: \[ 16k + 4 \geq 33k - 9 \] ### Step 3: Rearrange the inequality Next, we will rearrange the inequality to isolate \( k \). We will move all terms involving \( k \) to one side and constant terms to the other side. \[ 16k + 4 - 33k + 9 \geq 0 \] This simplifies to: \[ -17k + 13 \geq 0 \] ### Step 4: Isolate \( k \) Now, isolate \( k \) by moving the constant to the other side: \[ -17k \geq -13 \] ### Step 5: Divide by -17 When dividing by a negative number, we must reverse the inequality sign: \[ k \leq \frac{13}{17} \] ### Final Answer Thus, the solution to the inequality is: \[ k \leq \frac{13}{17} \]

To solve the inequality \( \frac{2(4k+1)}{3} \geq \frac{k(6+5)-3}{2} \), we will follow these steps: ### Step 1: Eliminate the fractions To eliminate the fractions, we will multiply both sides of the inequality by the least common multiple (LCM) of the denominators, which is 6. \[ 6 \cdot \frac{2(4k+1)}{3} \geq 6 \cdot \frac{k(6+5)-3}{2} \] ...
