I'm so confused please help!
6y=8-9+6y
2 answers:
Simplifying
6y = 8 + -9 + 6y
Combine like terms: 8 + -9 = -1
6y = -1 + 6y
Add '-6y' to each side of the equation.
6y + -6y = -1 + 6y + -6y
Combine like terms: 6y + -6y = 0
0 = -1 + 6y + -6y
Combine like terms: 6y + -6y = 0
0 = -1 + 0
0 = -1
Solving
0 = -1
Couldn't find a variable to solve for.
This equation is invalid, the left and right sides are not equal, therefore there is no solution.

Answer: Angles A and C are vertical angles.
Step-by-step explanation:
volume of a sphere = 4/3 *pi * r^3
3/4 * pi = 4/3 *pi * r^3
divide each side by pi
3/4 = 4/3 * r^3
multiply each side by 3/4
3/4 * 3/4 = r^3
9/16 = r^3
take the cube root of each side
r = (9/16) ^ (1/3)
