Answer: the length of Maria's piece of string is 45 inches.
the length of Katy's piece of string is 39 inches
Step-by-step explanation:
Let x represent the length of Maria's piece of string.
Let y represent the length of Katy's piece of string.
When they put the two pieces of string together end to end, the total length is 84inches. This means that 
x + y = 84 - - - - - - - - - - - -1
Maria's string is 6 inches longer than Katy's. This means that 
x = y + 6
Substituting x = y + 6 into equation 1, it becomes
y + 6 + y = 84
2y + 6 = 84
2y = 84 - 6 = 78
y = 78/2 = 39
x = y + 6 = 39 + 6
x = 45
 
        
             
        
        
        
10% of $2,000 is $200.
30%=3*10%
Therefore:
30% of $2,000 is $600.

Answer:
   x = 30
Step-by-step explanation:
Supplementary angles total 180°.
   5x° +x° = 180°
   6x = 180
   x = 180/6 = 30
The value of x is 30.
