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.

Answer:
Y = 5
Step-by-step explanation:
Since we know six is the value of X we can go ahead and multiply 4 and 6
4 X 6 = 24
Now there are different ways to find the value of Y
How I find the value is I subtracted 24 from 9
That gives you 15
Next you find what number you need to multiply by 3 to get 15
In this case your answer is 5
Then to be extra sure subtract 24 and 15 and you'll get 9
Hope this helps!
y = 5
substitute x = 6 into the equation and solve for y
(4 × 6 ) - 3y = 9
24 - 3y = 9 ( subtract 24 from both sides )
- 3y = - 15 ( divide both sides by - 3 )
y = 5

2/3 x +10/60 =100/60
Answer:
2 1/4
Step-by-step explanation:
subtract 10/60 from each side to get:
2/3x = 90/60
multiply each side by 3/2 to get:
x = 270/120
x = 27/12 or 2 1/4
