Add each term and divide it by 2.
5+7 = 12
12/2 = 6
-2 + 6 = 4
4/2 = 2, then add the i back on to get 2i.
The midpoint is 6 + 2i
Answer: 
.
Step-by-step explanation:
Let x=0.1282828...
Multiply 10 on both sides , we get
10 x = 1.282828... (i)
Now multiply 100 on both sides , we get
1000x=128.2828... (ii)
Eliminate (i) from (ii), we get
Hence, the required 
form: .
12.5/x = 25/100
cross multiply 12.5 and 100.
12.5×100=1250
the divide 1250 by 25
1250÷25=50
the answer would be 50.
I hope this helped : )
Four CDs must be bought to receive a gift card from an <em>online</em> store.
<h3>How to determine the least number of CDs to be bought to receive a gift card</h3>
The <em>total</em> costs are equal to the sum of the <em>shipping</em> cost and the total related to the number of <em>acquired</em> CDs (n). The number of gift cards (m) is equal to the total costs divided by <em>minimum spent</em> money, that is, $ 50. We need to solve the following inequation to find the minimum quantity of CDs:
(12 · n + 5)/50 > 1
12 · n + 5 > 50
12 · n > 45
n > 45/12
n > 3.75

Answer:
A negative number that is 12 less than its square is -3.
Step-by-step explanation:
This is because (-3)² = 9 and 9 - 12 = -3.
You can get this answer by testing different number until one works in the given situation. This is done by testing numbers by squaring them and then subtracting 12 to see if it equals the original number.
