Question

3.4k+(0.63−0.81k)÷0.9=5.7

Answer 1

The answer is k = 2

Answer 2

Answer:

k = 1.93 which can be rounded up to 2

Step-by-step explanation:

3.4k + (0.63 − 0.81k) ÷ 0.9 = 5.7        You don't need parentheses because you can't distribute

3.4k + 0.63 − 0.81k ÷ 0.9 = 5.7          Combine like terms

2.59k + 0.7 = 5.7                                

          - 0.7  - 0.7                                Subtract 0.7 from both sides

2.59k = 5                                             Divide both sides by 2.59

k = 1.93 which can be rounded up to 2
