2. System of equations

  • Setting equations equal to each other

To succeed in the SAT math no calculator section, you need to know when to set two equations equal to each other to find a solution. As an example, you may need to set two variables, such as price per pound of beef and chicken, equal to each other to find a solution.

🚀 Example
You may encounter a problem like this: "Beef costs $3 per pound and chicken costs $2 per pound. If you spent the same amount in buying 10 pounds of beef and \(c\) pounds of chicken, how much chicken did you buy?" In this case, you would set the total costs of beef and chicken equal to each other to find the weight of chicken. The equation would be:
\[\$3/\text{pound} \times 10 \text{ pounds} = \$2/\text{pound} \times c \text{ pounds}.\]
To solve for the weight of chickcen:\[\$30 = \$2c.\]
\(\text{Weight of chicken}(c)= 15\text{ pounds}\).
  • Simplifying equations

Simplifying equations is an important strategy for making them more manageable and easier to solve on the SAT math no calculator section. This involves using techniques like cross-multiplication and combining like terms to simplify equations and isolate variables. In order to effectively simplify equations, you need to have a strong foundation in algebraic operations.

🚀 Example
Given an equation like \(2.35 + 0.25x = 1.75 + 0.40x\), you can simplify it by subtracting \(0.25x\) from both sides to get:\[2.35 = 1.75 + 0.15x.\]

Then, you can subtract \(1.75\) from both sides to isolate the variable:\[0.60 = 0.15x.\]

Finally, you can divide both sides by \(0.15\) to solve for \(x\):\[x = 4.\]
  • Using substitution

To simplify SAT math problems that involve multiple equations, you can use substitution. Start by isolating one of the variables in one of the equations, and then substitute its value into the other equation.

🚀 Example
Start with the two given equations: \( y - 4 = 3x \) and \( 2x + y = 10 \).
Isolate \( y \) in the first equation by adding \( 4 \) to both sides: \( y = 3x + 4 \).

Substitute the resulting expression \( y = 3x + 4 \) into the second equation in place of \( y \), giving you: \( 2x + (3x + 4) = 10 \).

Simplify the equation by combining like terms: \( 5x + 4 = 10 \), which is equivalent to \( 5x = 6 \).

Solving for \(x\): \( x = 1.2 \).

This method of substitution eliminates one variable, making it easier to solve for the remaining variable.

3. Geometry and trigonometry

  • Understanding graphs and slopes

You should recognize the importance of graphing to visualize problems and understand the concept of slope as "rise over run."

🚀 Example
You may encounter a problem where you need to graph a line with a slope of \(\frac{1}{7}\):
Start at the y-intercept \((0,0)\).

Move up one unit and to the right seven units to find another point on the line.

Plot the two points \((0,0)\) and \((7,1)\).

Draw a straight line through the two points.

This line has a slope of \(\frac{1}{7}\) and passes through the points \((0,0)\) and \((7,1)\).
  • Using trigonometric identities

You should be able to understand that the sine of an angle is equal to the cosine of its complement and use this relationship to solve problems.

One example of using the trigonometric identity \(\sin x = \cos(90^{\circ}-x)\) is: Given that \(\sin 30^{\circ} = 0.5\), find \(\cos 60^{\circ}\).
Recognize that \(\cos 60 ^{\circ}\) is equal to \(\sin 30 ^{\circ} = 0.5\).

  • Solving for angles and sides

To find the lengths of sides in a triangle, you can rely on a handy tool known as SOHCAHTOA. It offers a simple way to remember how to utilize sine, cosine, and tangent in trigonometry.

🚀 Example
Let's say you have a right triangle, and you're given that \(\sin x = \frac{4}{5}\). With this information in hand, you can determine the lengths of the sides.

Remember that SOHCAHTOA states that sine equals the opposite side divided by the hypotenuse. So, by labeling one side as '\(l\)' and the hypotenuse as '\(h\),' you can set up the following equation:\[\frac{4}{5} = \sin x = \frac{l}{h}.\]

By solving for '\(h\),' you'll obtain:\[h = \frac{5l}{4}.\]

This approach empowers you to find the side lengths in your triangle using trigonometry, making it a valuable tool for tackling similar problems.

4. Polynomials

  • Recognizing polynomial forms

When it comes to polynomials, you can start by understanding their standard form. This helps you recognize coefficients and constants within a polynomial equation.

For instance, take a polynomial like \(ax + bx\), and you can simplify it by finding their sum.

  • Simplifying and expanding

Learning techniques to simplify or expand polynomials is another essential skill. It makes solving polynomial equations easier and more manageable.

For example, the expression:\[ax + bx\]

This is where you can find their sum.

  • Using factorization

Factorizing polynomials is of great importance when it comes to solving for variables.

Consider the equation:\[8B - B^2 = 15\]

This is where factorization becomes a powerful method to solve for \(B\). By grasping these aspects of polynomials, you'll be better equipped to work with them effectively.
