In order to isolate k, we would first cross multiply
3*k=9*10 
3k=90
Then to isolate k, we would divide both sides by 3 to get:
K=30
Hope this helps
        
                    
             
        
        
        
Given:
<span>F= $335,000 
n = 30 years at a fixed rate of i = 7.5% 
Required:
the total cost of the principal 
Solution:
F = P(1+i)^n
P = F/(1+i)^n
P = 335,000 / (1.0.075)^30
P = 38,264.05</span>

Answer:
-45
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable.
 
        
             
        
        
        
12/16, 
6/8,
3/4, and
45/60
are all equivalent to 24/32.
Now that I've listed those four, there are 
only an infinite number of others remaining.
