Study Notes
Translating Sentences into Equations
- When translating sentences into equations, identify keywords indicating mathematical operations.
- "More than" or "sum" signify addition.
- "Less than" or "difference" indicate subtraction.
- "Times" or "product" represent multiplication.
- "Quotient" denotes division.
- "Is" or "equals" are replaced with an equal sign (=).
Example Sentences:
-
"Five more than three times a number is 26"
- "Five more" translates to + 5.
- "Three times a number" translates to 3 * x (where x represents the unknown number).
- "Is" translates to =.
- The equation is 3x + 5 = 26.
-
"Six less than five times the number is nine"
- "Five times the number" translates to 5 * x.
- "Six less than" translates to - 6.
- "Is" translates to =.
- The equation is 5x - 6 = 9.
-
"The difference between four times a number and seven is five"
- "Four times a number" translates to 4 * x.
- "The difference between... and seven" translates to 4x - 7.
- "Is" translates to =.
- The equation is 4x - 7 = 5.
-
"Seven more than the quotient of a number and three is ten"
- "The quotient of a number and three" translates to x / 3.
- "Seven more than" translates to + 7.
- "Is" translates to =.
- The equation is x / 3 + 7 = 10.
-
"Five less than three times the sum of a number and four is twenty-two"
- "The sum of a number and four" translates to (x + 4).
- "Three times the sum of a number and four" translates to 3 * (x + 4).
- "Five less than" translates to - 5.
- "Is" translates to =.
- The equation is 3(x + 4) - 5 = 22.
Solving Equations
- Use the order of operations (PEMDAS/BODMAS) to solve equations.
- Combine like terms on each side of the equation.
- Employ inverse operations to isolate the variable (x).
- Addition and subtraction are inverse operations.
- Multiplication and division are inverse operations.
Practice Makes Perfect
- Consistent practice is crucial for confidently translating sentences into equations.
- Working through numerous examples improves proficiency.
