Answer:
The first envelope contained $300 and the second envelope contained $200.
Step-by-step explanation:
3/5 of $300 is $180, so you subtract that from $300 to get a sum of $120.
Then you subtract $80 from $200 to get a sum of $120.
Therefore:
The first envelope contained $300 and the second contained $200.
Have a good day! :)
Answer:
The answer to your question is: x1 = - 7 + 9i x2 = -7 - 9i
Step-by-step explanation:
x² + 14x = - 130
x² + 14x + (7)² = -130 + (7)²
(x + 7)² = -81
x + 7 = ± √-81
i² = -1, then x + 7 = ±√ 81i²
x + 7 = ± 9i
x1 = -7 + 9i x2 = -7 - 9i
Look at the right and see how the numbers are going down 1,000 each number.
I hope this helps you out
