Answer:
x = 3
Step-by-step explanation:
Mathematically, the mean is the sum of the numbers divided by the count of the numbers
The count of the numbers is 5
Thus;
( 4 + 8 + 9 + x + 2x)/5 = 6
(21 + 3x)/5 = 6
21 + 3x = 6(5)
21 + 3x = 30
3x = 30-21
3x = 9
x = 9/3
x = 3
Answer:
x=4.5
Step-by-step explanation:
The sum of all the angles in a square=360°
20(4.5)=90
90×4=360
Answer:
1/2
Step-by-step explanation:
![y = \sqrt[3]{\frac{1}{8x}}\\\\=\sqrt[3]{\frac{1}{2*2*2*x}}\\\\=\frac{1}{2}\sqrt[3]{\frac{1}{x}}](https://tex.z-dn.net/?f=y%20%3D%20%5Csqrt%5B3%5D%7B%5Cfrac%7B1%7D%7B8x%7D%7D%5C%5C%5C%5C%3D%5Csqrt%5B3%5D%7B%5Cfrac%7B1%7D%7B2%2A2%2A2%2Ax%7D%7D%5C%5C%5C%5C%3D%5Cfrac%7B1%7D%7B2%7D%5Csqrt%5B3%5D%7B%5Cfrac%7B1%7D%7Bx%7D%7D)
Constant of proportional= 1/2
