½(4k + 3r) ÷ 3^1 k = 9 r = 6 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

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

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

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

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

$\\ = 9$
