½(4k + 3r) ÷ 3^1<br><br> k = 9<br> r = 6<br><br> show work
vampirchik [111]

Answer:

The solution is given below:

Step-by-step explanation:

\\ \frac{1}{2} (4k + 3r) \div  {3}^{1}

As we know the value of k and r so the equation will be

\\ \frac{1}{2} (4 \times 9 + 3 \times 6) \div  {3}^{1}

\\  =  \frac{1}{2} (36 + 18) \div 3

\\  =  \frac{1}{2} \times 54 \div 3

\\  =  \frac{1}{2}  \times 18

\\  = 9
