Lesson Review

Directions: Solve the following equations by using the rules for removing the parentheses.

1. 2(x - 3) = 32

2. 6(2x + 4) = 24

3. 3(3s + 4) = 21

4. 6(c - 2) = 4(c + 3)

5. 12(r - 3) = 6(r + 3)

6. 3(x + 5) = 30

7. 6(b + 2) = 3(b-2)

8. 2(c - 2) = 16

9. 4(y + 2) = 28

10. 2(d - 2) = 2(d + 3)

11. 5(L + 5) = 35

12. 2(k - 2) = 44

13. p - 9 = 11

14. 3(s + 3) = 27

15. 5(a - 3) = 45

since both sides equal, there are infinitely many olutions.

well if he bought them at 5 cedis each sold them at 7 cedis each then he would make a profit of 2 cedis of each book. if in total he made 150 cedis profit that means he sold 75 books. he lost 12 books at the start so that means he originally bought a total of 82 books.

step-by-step explanation:

the answer is d.x= 90°

y= 50°

arc lm= 100°
