Study Notes
Mathematical Expressions
- The product of 5 and x is represented as 5x.
- 22% of a is expressed as 0.22a.
Algebraic Expressions
- "8 more than the product of 6 and n" translates to 8 + 6n.
Evaluation of Expressions
- For m = 30, evaluating 30 - m/6 results in 25.
- Substituting a = 2, b = 5, c = 4 into ab + c yields 14.
- For x = 6, y = 9, z = 2, evaluating x(y + 3) / (3 + y)z results in 3.
- For F = 9/5c + 32 with c = 30 degrees, the result is 86 degrees.
Solving Equations
- To solve for x in the equation 3x = -9, x equals -3.
- For the equation x - 2 = 10, solving for x gives 12.
- Solving 1/3x = 10 results in x being 30.
