Study Notes
Translating Words into Algebraic Expressions
- The primary focus of the lesson is on translating words into algebraic expressions.
Algebraic Language
- Algebraic language uses symbols to express ideas and simplify problem resolution.
Examples of Translating Words
- An excellent example of translating words into algebraic expressions is converting phrases into mathematical equations.
Mathematical Concepts
- Words are not expressed through symbols in algebraic language.
Physics and Algebra
- Newton's second law of motion states that the force applied to an object is equal to the mass of the object multiplied by its acceleration.
Price of Gas
- The price of gas per liter depends on several factors.
Algebraic Symbols
- The symbol 'x' represents an unknown value or variable in algebra.
- Mathematical symbols such as (+, -, x, ) represent operations or relationships between variables.
Word Problems
- Word problems should be translated into algebraic equations to solve them efficiently.
Lesson Focus
- The lesson focuses on translating words into algebraic expressions.
Translating Phrases
- The phrase 'The price of a car in the US is smaller than the price for the same car in Brazil (in dollars)' can be represented algebraically as US < Brazil.
- The phrase 'The net income results from the subtraction of the taxes from the gross income' can be represented algebraically as Net Income = Gross Income - Taxes.
- The phrase 'A discount of 20 percent in any item' can be represented algebraically as Price = Original Price - (20% of Original Price).
- The total amount of tips received by a restaurant after a month divided among all employees can be represented algebraically as Total Tips / Number of Employees = Tips per Employee.
- The phrase 'Josh bought 12 pieces of fruit when adding up the apples and bananas purchased' can be represented algebraically as Apples + Bananas = 12.
