cos (3pi x/3) = 0.5
The number of answers depends on the range of angles. I will solve this question using the range 0<x<2 pi. Draw a unit circle, you will see that the quadrants where cosine gives a positive value are the first and the fourth quadrants.
The Angles whose cosines give + 0.5 are: pi / 3 and 5pi / 3. (Note that 7 pi/3 and 11 pi/3 are also possible solutions but they lie out of the range 0<x<2pi.)
3pi x/3 = pi/3 OR 3pi x/3 = 5pi/3
Here you can solve the equations to give x = 1/3; 5/3

Is the number 1 over 9 a solution to the equation 27x-5 equals 4?
No. The solution to the equation is 1/3. To solve: 27x - 5 = 4 (add 5 to each side to separate knownsa from inkowns) 27x = 9 (now divide both sides by 27 to find the value of x) x = 1/3 (solution)
How you find the equation of X over 5 equals 3?
You multiply both sides by 5 to clear the fraction and get the answer x equals 15.
Does the equation 4x equals -20 have a solution over the set of rational numbers?

How do you find the mean of x over y equals a over b?
Find the derivative of Y and then divide that by the derivative of A
What is 2 over x plus 1 over 3 equals 4 over x?
It's an algebraic equation in one variable. [ x=6 ] is its solution.
Is the number 1 over 9 a solution to the equation 27x-5 equals 4?
No. The solution to the equation is 1/3. To solve: 27x - 5 = 4 (add 5 to each side to separate knownsa from inkowns) 27x = 9 (now divide both sides by 27 to find the value of x) x = 1/3 (solution)
What is the solution to x over 4 minus 4 equals x over 4?
x/4 - 4 = x/4 4x/4 - 4 x 4 = x x - 16 = x 0 = 16 There is no solution to the equation.
What is the solution of 2 times 22 over 7 equals?
2 x 22/7 = 44/7 or 6 2/7
How you find the equation of X over 5 equals 3?
You multiply both sides by 5 to clear the fraction and get the answer x equals 15.
