Explanation Procedure used: “1. UNDERSTAND: Some ways of doing this are to read and reread the problem, construct a drawing, and look for key words to identify an operation. 2. TRANSLATE: Write the problem in short form using words, and then translate to numbers and symbols. 3. SOLVE: It is helpful to estimate the solution by rounding. Then carry out the indicated operation from step 2. 4. INTERPERT: Check the proposed solution in the stated problem and state your conclusions. Write your results with the correct units attached.” Calculation: 1. UNDERSTAND: The given sentence is “Three times a number, added to 9, is 33”. Suppose that the unknown number is x . The sum of 3 x and 9 is equal to 33. 2. TRANSLATE: The sentence can be translated as follows. In words: Three ︸ ↓ times ︸ ↓ a number ︸ ↓ added to ︸ ↓ 9 ︸ ↓ is ︸ ↓ 33 ︸ ↓ Translate: 3 ⋅ x + 9 = 33 Thus, the sentence can be translated to an equation as 9 + 3 x = 33 _

Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
