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
