Answer:
Step-by-step explanation:
Given
Orchestral = 
of music practice time
Required
Determine time spent on orchestral pieces
From the given parameters, we have:
Orchestral = of music practice time
Substitute 
for music practice time.
So, we have:
Since it requires 2 days to jar 12 liters of jam, if we want to find out how many days it takes to jar 48 liters, we divide 48 by 12 and get 4.
Then we multiply 4 by 2 and get 8 days. It took 8 days to fill 48 liters of jam.
12/2 = 48/x
12x = 96
x = 8
Step-by-step explanation:
The following is a list of perfect Cubes
13 = 1
23 = 8
33 = 27
43 = 64
53 = 125
63 = 216
73 = 343
83 = 512
93 = 729
103 = 1000
If a variable with an exponent has an exponent which is divisible by 3 then it is a perfect cube. To get the cube root, we simply divide the exponent by 3. For example x9 is a perfect cube, its cube root is x3 . x11 is not a perfect cube.
