Question

# Show the conjecture is false by finding a counterexample. Two adjacent angles always form a linear pair.

## The correct answer is: Hence, the counterexample for the given conjecture is the above figure.

### Linear pairs are always supplementary but adjacent angles may not be. It can be shown by the following

diagram:

Here, we can see that the sum of adjacent angles will be definitely less than 180^{o}. So, the given conjecture is wrong.

Final Answer:

Hence, the counterexample for the given conjecture is the above figure.

original price of the calculator?

The x + 2 = 6 x+2=6x, plus, 2, equals 6 contains a variable. We call this type of equation with a variable an algebraic equation. Finding the variable value that will result in a true equation is typically our aim when solving an algebraic equation.

¶Variables or constants are the two types of measurable quantities. A variable is a quantity with a varying value, and the constant value is nothing but a constant.

¶**Steps to writing Variable Equation**

1) Identify the variables that represent the unknowns.

2) Convert the issue into variable expressions in algebra.

3) Determine the variables' values to solve the equations for their true values.
