Take the log (base 4) of both sides of the equation.



The appropriate choice is ...
  m = -11/4
 
        
        
        
Answer:
528
Step-by-step explanation:
(80:100)*660 =
(80*660):100 =
52800:100 = 528
Now we have: 80 percent of 660 = 528
 
        
             
        
        
        
Answer:
a = 30
b = 40
C
Step-by-step explanation:
This requires that you use a proportion.
a / (a + 15) = 40 / 60
The small triangle's sides are in proportion to the large triangles sides.
Reduce the right. Divide top and bottom by 20
a/(a + 15) = 40/20 // 60/20
a/(a + 15) = 2/3                     
Cross multiply
3a = 2(a + 15)            Remove the brackets on the right.
3a = 2a + 30
Subtract 2a from both sides
3a-2a = 30
a = 30
Find B
b is done exactly the same way.
b/(b+20) = 2/3 
3b = 2b + 40
3b - 2b = 40
b = 40
