2sinA - 1 = 0
2sinA = 1
sinA = 0.5
so A = sin-1(0.5) and
so A = pi/6 + 2n*pi radians
or A = 5pi/6 + 2n*pi radians
for all integer values of n.
Equivalently,
A = 30 + 360n degrees
or 150 + 360n degrees for all integer values of n.
6The line of best fit has the equation = -3 + 2.5x. What does this equation predict for a value of x = 3?Answer: 4.5
x = 9/2 or x = -2 Solved by using the quadratic equation formula.
You cannot solve this equation without knowing the shape.
There are no exclude values of the equation, as given.
It is an equation and the value of x works out as 88

There is no value of x that satisfies the equation. You may be missing an operator (+. - sign).
To find the value of "what" in the equation "what - what equals 477," we can set it up as "x - x = 477." However, since any number minus itself equals zero, there is no value of "what" that satisfies this equation. Therefore, the equation is not solvable in standard arithmetic.
It is the solution of the given equation.
5a - 1 = a - 7 4a = -6 a = -1.5
a solution
To find what times 5 equals 400, you can set up the equation as x * 5 = 400. To solve for x, you would divide both sides of the equation by 5, giving you x = 400 / 5. Therefore, the value of x that satisfies the equation is x = 80.
If you mean: 2x+5+3x = 25 then the value of x works out as 4
To find the value of x when multiplied by 7 equals 144, you can set up the equation 7x = 144. To solve for x, divide both sides by 7: x = 144 / 7 = 20.57. Therefore, the value of x that satisfies the equation 7x = 144 is approximately 20.57.
If you found the value of x that is a solution to an equation, you want to substitute that value back into the original equation, to check that it indeed satisfies the equation. If it does not satisfy the equation, then you made an error in your calculations, and you need to rework the problem.

Only one value of x satisfies this [x = 3], but y is not specified, so y can be any value. In a 2 dimensional plane, this would be a vertical line at x = 3
