Math lesson- One thing I can improve on

One thing I think I can improve on is the relationship I have between my friends and I. After today's activity, I realized I am not one who usually initiates but usually let others start first. I think I also need to accept the fact that all my friends are different in their own way so I should not expect all of them to act the same.

Another thing I also think I can improve on is my time management at home and knowing how to priorities my work and rest time.

Chapter 4: Algebra Puzzle

3x3:

Let y be car, p be ice cream and q be umbrella.

• 3y=18

y=18/3

y=6

• 2y+p=21

(2x6)+p=21

12+p=21

21-12=p

p=9

• 2p+q=19

(2x9)+q=19

18+q=19

19-18=q

q=1

Therefore, each car represents 6, each ice cream represents 9 and each umbrella represents 1.

3x4:

Let y be the ladybug, p the gear and q the apple.

• 3y+p=93

2y+p=72

• (3y+p)-(2y=p)=y

93-72=21

y=21

• 2y+p=72

21x2+p=72

42+p=72

72-42+p

p=30

• 2y+q=55

42+q=55

55-42=q

q=13

Therefore, the ladybug represents 21, the gear represents 30 and the apple represents 13.
