The angles of a parallelogram add up to 360°
and the opposite angles are equal
so you make the equation: 150+150+5x+5x=360
you solve for x
10x=60
x=6
Let's say x = 16. In the equation 4 + x(3/x) then you use 16 instead of x. So it would look like 4 + 16(16/3). 4 plus 16 times 16 divided by 3.
Can you restate the question
Answer:
The equation (i) is the only algebraic equations.
Step-by-step explanation:
From the given examples of equations the equation (i) is the only algebraic equations.
(i) 3.1x - 11.2 = 2.5x + 2.3.
This is an example of algebraic equation with single variable x.
(ii) ???? + ???? = 2????
This could be an equation with variable ???? but both the sides being equal they cancel each other and no equation remains.
(iii) 1/2 +1/2 = 2/4
This is not an algebraic equation since there is no variable. (Answer)
8.5 * x = 5
5 / 8.5
Approximately 10/17
