GEOGRAPHY

On Friday, the class took notes over socio-economic factors. No homework.

PRE-ALGEBRA

We finished the test review. The equations and expressions test is on Monday. Here are the last three problems that we didn't get to:

22.

12 + 8 -3g = 7g + g - 13

20 - 3g = 8g - 13      (combine like terms on each side. 12 + 8 on the left and 7g + g on the right.)
     + 3g   +3g
20 = 11g - 13    (move the -3g to the right side by adding 3g to both sides)
+13         + 13

33 = 11g         move the -13 to the left side

divide both sides by 11 to get the g by itself. The answer is:

3 = g

23.

9y + 2 - 5y = -13 + y + 6

4y + 2 = -7 + y      (combine 9y -5y on the left to get 4y and -13 + 6 to get -7 on the right)
-y                -y

3y + 2 = -7         (move the +y on the right side to the left by subtracting it on both sides.)
     -2      -2

3y = -9       (move the +2 to the right side by subtracting 2 from both sides.)

y = -3      (divide both sides by 3)

25. 7(3b - 2) + 10 = -(3b -20)

21b -14 + 10 = -3b +20    (distribute the 7 to the 3b and -2 to get 21b -14. Then distribute the
                                          negative sign to the 3b - 20. It changes BOTH signs so you have -3b + 20.

21b -4 = -3b + 20 (combine like terms on the left side -14 + 10 = -4)
+3b        +3b        

24b - 4 = 20    (get the -3b to the left side by adding 3b to both sides.)
       +4     +4

24b = 24         (move the 4 to the right side by adding 4)

b = 1           (divide both sides by 24)

See you on Monday,
