667.302 would be the correct answer, I did it in a calculator
Volume of a cube: V = s^3, where s is the length of the edge.
So, the sum of them will be 1^3 + 2^3 = 9
X = 3
Combine like terms: -4 + -5 = -9
-9 + 6x + -3x = 0
Combine like terms: 6x + -3x = 3x
-9 + 3x =0
Solving -9 + 3x = 0
Solving for variable ‘x’
Moving all terms containing my x to the left, all other terms to the right
Add ‘9’ to each side of the equation -9 + 9 + 3x = 0 + 9
Combine like terms: -9 + 9 = 0
0+3x=0+9
3x = 0 + 9
Combine like terms: 0 + 9 = 9
3x = 9
Divide each side by ‘3’.
X = 3
SORRY THIS IS SO LONG
You'll need to isolate 9a on the left side of this equation
Please add 7 to both sides of the eqn, obtaining 9a = 117.
Solve for a by dividing both sides by 9: a = 117/9 = 13 (answer)
The mean is : 26
53 + 29 + 11 + 13 + 24 = 130
130 / 5 = 26
