Mathematical expressions can often be complex and difficult to understand. Simplifying and rearranging these expressions is an essential skill in mathematics, as it allows us to better comprehend the underlying relationships between variables and constants. In this article, we will explore how to simplify and rearrange five different mathematical expressions.

Expression 1: Simplifying a Multiplication and Division Expression

The first expression we will simplify is:

$$3 \cdot L_{0 / ve} \div 32$$

To simplify this expression, we need to follow the order of operations (PEMDAS):

1. Multiply 3 and $L_{0 / ve}$: $3 \cdot L_{0 / ve} = 3L_{0 / ve}$
2. Divide the result by 32: $\frac{3L_{0 / ve}}{32}$

Therefore, the simplified expression is:

$$\frac{3L_{0 / ve}}{32}$$

Expression 2: Rearranging an Inequality

The second expression we will rearrange is:

$$4a \leqslant \frac{3}{4}$$

To rearrange this inequality, we need to isolate the variable $a$ on one side of the inequality. We can do this by dividing both sides of the inequality by 4:

$$a \leqslant \frac{3}{16}$$

Therefore, the rearranged inequality is:

$$a \leqslant \frac{3}{16}$$

Expression 3: Solving for a Variable

The third expression we will solve is:

$$4 = 32b$$

To solve for the variable $b$, we need to isolate $b$ on one side of the equation. We can do this by dividing both sides of the equation by 32:

$$b = \frac{4}{32}$$

Simplifying the fraction, we get:

$$b = \frac{1}{8}$$

Therefore, the solution to the equation is:

$$b = \frac{1}{8}$$

Expression 4: Solving for a Variable

The fourth expression we will solve is:

$$10c = 26$$

To solve for the variable $c$, we need to isolate $c$ on one side of the equation. We can do this by dividing both sides of the equation by 10:

$$c = \frac{26}{10}$$

Simplifying the fraction, we get:

$$c = \frac{13}{5}$$

Therefore, the solution to the equation is:

$$c = \frac{13}{5}$$

Expression 5: Solving for a Variable

The fifth expression we will solve is:

$$26 = 100d$$

To solve for the variable $d$, we need to isolate $d$ on one side of the equation. We can do this by dividing both sides of the equation by 100:

$$d = \frac{26}{100}$$

Simplifying the fraction, we get:

$$d = \frac{13}{50}$$

Therefore, the solution to the equation is:

$$d = \frac{13}{50}$$

Final Thoughts

In this article, we will answer some of the most frequently asked questions about simplifying and rearranging mathematical expressions.

Q: What is the order of operations?

A: The order of operations is a set of rules that tells us which operations to perform first when simplifying a mathematical expression. The order of operations is:

1. Parentheses: Evaluate expressions inside parentheses first.
2. Exponents: Evaluate any exponential expressions next.
3. Multiplication and Division: Evaluate any multiplication and division operations from left to right.
4. Addition and Subtraction: Finally, evaluate any addition and subtraction operations from left to right.

Q: How do I simplify a fraction?

A: To simplify a fraction, you need to divide both the numerator and the denominator by their greatest common divisor (GCD). The GCD is the largest number that divides both the numerator and the denominator without leaving a remainder.

Q: How do I isolate a variable on one side of an equation?

A: To isolate a variable on one side of an equation, you need to perform inverse operations to get the variable by itself. For example, if you have the equation:

$$2x + 3 = 5$$

You can isolate the variable $x$ by subtracting 3 from both sides of the equation:

$$2x = 5 - 3$$

$$2x = 2$$

Then, you can divide both sides of the equation by 2 to get:

$$x = \frac{2}{2}$$

$$x = 1$$

Q: What is the difference between an equation and an inequality?

A: An equation is a statement that says two expressions are equal, while an inequality is a statement that says one expression is greater than or less than another expression.

For example:

$$2x + 3 = 5$$

is an equation, while:

$$2x + 3 > 5$$

is an inequality.

Q: How do I solve a linear equation?

A: To solve a linear equation, you need to isolate the variable on one side of the equation. You can do this by performing inverse operations, such as adding or subtracting the same value to both sides of the equation, or multiplying or dividing both sides of the equation by the same value.

For example, to solve the equation:

$$2x + 3 = 5$$

You can subtract 3 from both sides of the equation:

$$2x = 5 - 3$$

$$2x = 2$$

Then, you can divide both sides of the equation by 2 to get:

$$x = \frac{2}{2}$$

$$x = 1$$

Q: How do I solve a quadratic equation?

A: To solve a quadratic equation, you need to use the quadratic formula:

$$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$

where $a$, $b$, and $c$ are the coefficients of the quadratic equation.

For example, to solve the equation:

$$x^2 + 4x + 4 = 0$$

You can use the quadratic formula:

$$x = \frac{-4 \pm \sqrt{4^2 - 4(1)(4)}}{2(1)}$$

$$x = \frac{-4 \pm \sqrt{16 - 16}}{2}$$

$$x = \frac{-4 \pm \sqrt{0}}{2}$$

$$x = \frac{-4}{2}$$

$$x = -2$$

Q: What is the difference between a linear equation and a quadratic equation?

A: A linear equation is an equation in which the highest power of the variable is 1, while a quadratic equation is an equation in which the highest power of the variable is 2.

For example:

$$2x + 3 = 5$$

is a linear equation, while:

$$x^2 + 4x + 4 = 0$$

is a quadratic equation.

Q: How do I graph a linear equation?

A: To graph a linear equation, you need to find two points on the line and plot them on a coordinate plane. You can then draw a line through the two points to graph the equation.

For example, to graph the equation:

$$y = 2x + 3$$

You can find two points on the line by plugging in different values of $x$ and solving for $y$. For example, if you plug in $x = 0$, you get:

$$y = 2(0) + 3$$

$$y = 3$$

So, the point $(0, 3)$ is on the line. If you plug in $x = 1$, you get:

$$y = 2(1) + 3$$

$$y = 5$$

So, the point $(1, 5)$ is also on the line. You can then plot these two points on a coordinate plane and draw a line through them to graph the equation.

Q: How do I graph a quadratic equation?

A: To graph a quadratic equation, you need to find the vertex of the parabola and plot it on a coordinate plane. You can then draw a parabola through the vertex to graph the equation.

For example, to graph the equation:

$$y = x^2 + 4x + 4$$

You can find the vertex of the parabola by using the formula:

$$x = \frac{-b}{2a}$$

where $a$ and $b$ are the coefficients of the quadratic equation.

In this case, $a = 1$ and $b = 4$, so:

$$x = \frac{-4}{2(1)}$$

$$x = -2$$

So, the vertex of the parabola is at the point $(-2, 0)$. You can then plot this point on a coordinate plane and draw a parabola through it to graph the equation.
