1. Adding and Subtracting Monomials

2. Activity 1: Who Am I? Rita, Rico, and Mary wanted to donate clothes to people who lost their belongings in a fire. Rita gave five pairs of pants, ten shirts, and four pairs of slippers. Rico gave six pairs of pants, 12 shirts, and seven pairs of slippers. Mary gave three pairs of pants, five shirts, and two pairs of slippers.

3. How many pairs of pants were donated by Rita and her friends?

4. Rita and her friends donated 14 pairs of pants

5. 2. How many shirts were given to the fire victims by Rita and her friends ?

6. Rita and her friends. donated 27 shirts.

7. 3. How many pairs of slippers have Rita and her friends given?

8. Rita and her friends. donated 13 pairs of slippers.

9. 4. What is the total number of goods or items that Rita and her friends have given?

10. Rita and her friends donated 14 pairs of pants, 27 shirts, and 13 pairs of slippers to the fire victims.

11. 5 . Why do you count the number of pants, shirts, and slippers separately instead of adding them altogether?

12. Because we cannot combine unlike items

13. Constants are the numerical coefficients of the variables or values that stay the same.

14. Variables are placeholders to represent unknown quantities. Variables are often expressed as letters, such as "𝑥" 𝑜𝑟 "𝑦.“

15. Like terms are defined as terms with the same variables and the same time similar exponents.

16. Unlike terms are terms that do not have the same variables and exponents.

17. Activity 2: Act on It! Mary bought a pair of shoes and a blouse from a department store. Each pair of shoes costs Php 1000.00, and each blouse costs Php 4 350.00. Write an expression for the total cost if you buy 𝑥 pair of shoes and 𝑦 blouse.

18. Guide Questions: Write an expression for the total cost. Explain how each part of the given is being represented. Identify its constants and variables, and decide if the variables are like or unlike terms. Explain your answer on question no. 3 about like or unlike terms.

19. 1000𝑥 + 350𝑦 A pair of shoes is represented as 1000𝑥, while a blouse is represented as 350𝑦. x and y are variables; the numbers 1000 and 350 are constant to the variable x and y, respectively, and x and y are unlike terms. Terms are unlike because they have different variables or the same variables raised to different exponents.

20. Read and understand the given problem, and answer the questions below. Jacob decided to rent a car for the family. It will cost Php 2500.00 for 12 hours and Php 200.00 for each additional hour. If Joel exceeds 5 hours on its basic rental costs, how much will he pay to the owner? Explain your answer

21. In the expression 9x + 4y, identify the constant and variables. Identify the variables in the expression 3x – 4z. In statement no. 2, write whether 3x and 4z are like or unlike terms. Explain your answer in no. 3. Compare like terms to, unlike terms.
