Answer:
x = 2 + 5i√2 / 6 and x = 2 - 5i√2 / 6
Step-by-step explanation:
If this isn't right, I'm sorry. Also, you can put x = 2 ± 5i√2 /6 to make it shorter and not have two answers. Hope this helps :)
 
        
             
        
        
        
The answer is f because if you find the average between 78 and 62 you get 70
        
             
        
        
        
Answer:
3/5   or
0.6
Step-by-step explanation:
You could change these fractions to decimals, but you may not be convinced that the answer you get is the same as just using fractions. I'll start by using fractions.
x - 2/5 = 1/5                        Add 2/5 to both sides
x - 2/5 + 2/5 = 1/5 + 2/5     The left side cancels to 0.
x = 1/5 + 2/5                       The denominators (bottom the fraction) are the same. Just add the tops.
x = (1 + 2)/5
x = 3/5
=======================
If you use your calculator to find 2/5 and 1/5, you can get the same answer as 3/5
2
÷
5
= 
0.4
By the same method, 1/5 = 0.2
Substitute into the original equation
x - 0.4 = 0.2                       Add 0.4 to both sides
x - 0.4 +0.4 = 0.2 + 0.4    The left side reduces just to x
x = 0.2 +0.4
x = 0.6
If you let your calculator do the work, like this
3
÷ 
5               
=
0.6
The answers are the same.
