### Algebra

1. 1. J. MBEDU 201246302 Authentic learning task for grade 10’s [Algebraic Equations] 2014/04/10J. MBEDU 201246302 1
2. 2. Algebraic Equations
3. 3. Basic Description of Equation constant variable exponent Equal Sign
4. 4. Factorizing
5. 5. Find factors of 8 1x8 2x4 4x2 8x4
6. 6. Expanding
7. 7. "Expanding" means removing the ( ). but you have to do it the right way! ( ) are called “Parentheses” or “Brackets” In Algebra putting two things next to each other usually means to multiply.
8. 8. ℎ ℎ
9. 9. Simplifying
10. 10. One of the big jobs we do in Algebra is "simplification What is the Simplest Form? write it in the most compact or efficient manner, without changing the value of the expression. In general, it is simpler if it is easier to use, Simplifying uses much the same skills as solving equations.
11. 11. Expand the top part first. Group the like (same) terms where possible
12. 12. Real World Relevance Word Problems
13. 13. 1. Lets say you need to buy a NEW Xbox 360. You have R800 to spend on everything. You know a new system costs R400 and extra controller R40. Assuming a game costs R60 how many games could you get?
14. 14. 2. Bob has R1,000 budgeted to pay for a bonus for his assistant, Carol. He wants to pay her such that after the business pays her and pays for the taxes for her, he has spent exactly R1,000. The business must pay taxes in the amount of 7.45% of her bonus. How much of a bonus will she get? Using algebra, we can say that Carol's bonus (C) plus the company's tax liability (T) equals R1,000. C + T = 1000 We also know that the company's tax liability (T) equals 7.45% of Carol's bonus (C), so; T = 0.0745 x C Substituting, C + (0.0745 x C) = 1000 C = 930.67

In the Class of Professional 3A we have an unknown number of students who Passed the first assessment given that the total number of all students participated is 5 (five) times the unknown number of students who failed. Now determine the number of students failed if 55 Students Passed.
36. 36. A. C. D. B. 2. Nomcebo and Samukelisiwe are carrying a huge bottle of Milk, they then decide to share the Milk but they don’t have a measuring cylinder Nomcebo Decide to pour the milk in her bottle measured 10 litres which 5 (five) times smaller than the huge bottle of milk.
37. 37. A. C. D. B. 3. In the Class of Professional 3A we have an unknown number of students who Passed the first assessment given that the total number of all students participated is 5 (five) times the unknown number of students who failed. Now determine the number of students Passed if 95 Students Failed.
38. 38. A. C. D. B. 1.
