1) The document is a student's Khan Academy progress report and homework assignments for the week. It includes time spent on Khan Academy each day, scores on recent problem sets, and upcoming homework topics. 2) The student needs to complete problems 2-4 and 2-5 from their math textbook and write topics to cover on Khan Academy this Saturday. 3) The final section reviews solving equations with fractions, showing an example of multiplying all terms by the denominator to clear the fractions.

1. Wednesday, September 26, 2012
Class Work:
Complete 2-4, 2-5
Write Khan topics for this Saturday

2. Very Impressed with your effort at Khan Academy.
Please Continue throughout this school year.
Day Minutes ÷ 60 = Hours
Tuesday (25th) 780 13
Monday (24th) 1125 18.75
Saturday (22nd) 1743 29.05

3. Did not correctly answer 8 questions in a row. Total
% Score: 8 Problems x 2 points each = 16%

4. Student tried 120 problems, but not 8 correct in a row. Student
earns maximum of 70%. 35 x 2 points each. Why try 120 if
max is 70%? If you get 8 consecutive before due date, = 100%

5. 1. Evaluate the expression when b = 5 and a = 6
9b + 7a + 7
(From Combining Like Terms with Distribution)
2. -1 - 2(-x + 5)
(From Properties of Numbers 1)
3. Name the property shown: a + b(c + d) = a + bc + cd
4. -1 - (-8)

6. 5. 6 - u = 2
7
6. 12 ÷ 22 - 4 + 3(1 + 2) 3
7. The sum of 8/9 and 12/13 is approximately what?

7. 1. Additive Inverse: What you add to a number to get zero.
The negative of a number. Ex: 14 + (-14)
The Additive Inverse Property: a + -a = 0, -a + a = 0
Also known as the Opposite
2. Multiplicative Inverse: A number multiplied by its
Multiplicative Inverse equals 1. Another name for the
reciprocal of a number. Ex: 8 x 1/8 = 1

8. Original Multiplicative Opposite &

9. Class Work:
 Complete 2-4, 2-5
 Write Khan topics for this Saturday

10. Finally, a review of solving equations with fractions.
Your goal is to get rid of the fractions. You do this by
multiplying each term by the number which removes the
denominator of the fraction.
1. ¾(x + 3) = 9 How many terms are there?
4{3/4(x + 3)} = 9 x 4 = 3(x + 3) = 36;
3x + 9 = 36; 3x = 27; x = 9
Solve: 3/2x + ½(x - 4) = 6
