Answer:
Determine if the sequence is arithmetic (Do you add, or subtract, the same amount from one term to the next?)
Find the common difference.
Step-by-step explanation:
The first answer is going to be 15.42 (so b) and the second is going to be 10.67 (so a)
Since the sign before the parentheses is a + , we can just remove the parentheses.
<span>5i + (-9 - i) = 5i - 9 - i = -<u>9 + 4i</u></span>
Answer:
I think you meant 40% off. If so...
Step-by-step explanation:
First, you have to turn 40 into a decimal - .40.
Then you multiply 30*.40 and get 12.
Subtract 12 from 30 since you are saving 12 dollars.
This means you spend $18 and saved $12.
So, your final answer would be $12.
Hope this helps :)
