Answer:
A - 19.5
Step-by-step explanation:
A Rhombus is characterized by the diagonals meeting at a right angle. Therefore, the angle in the center is 90 degrees.
If you look at the bottom triangle, you know that the angles of a triangle add up to 180 degrees. You can say that all of the angles of the triangle added to 180 are:
(3x + 12) + (x) +(90) = 180 degrees
4x + 102 = 180 degrees combining like terms
4x + 102 - 102 = 180 - 102
4x = 78
4x/4 = 78/4
x = 19.5 degrees

Answer:
Step-by-step explanation:
The equation is 7(2x-1) - 11 = 6 + 6x
The equation is a linear equation because the highest power of x is one.
x is the variable and the numbers not containing x are constants
To solve the equation,
First step is to distribute. This involves opening up the bracket.
7(2x-1) - 11 = 6 + 6x will become
7×2x - 7×1 - 11 = 6 + 6x
14x - 7 - 11 = 6 + 6x
Next step is to combine like terms
14x -18 = 6 + 6x
Next step is to move the variable terms to the left hand side of the equation and move the constant terms to the right hand side of the equation. It becomes
14x - 6x = 6 + 18
8x = 24
x = 24/8 = 3
Yes, you just have to multiply
