it's still confusing when you subtract it. at 8:00, can you give me a review test because tomorrow is my unit 9 test.

Please go back and study the information I've already posted. Also, be sure to study your book.

You'll find some percentage worksheets in these sites.

Of course! I can help you with a review test for your upcoming Unit 9 test. However, as an AI text-based bot, I am unable to provide interactive or real-time test-taking experiences. I can, however, simulate a test-like scenario by presenting you with a series of questions and providing explanations for the answers. Let's start with a few questions:

1. What is the largest planet in our solar system?
To answer this question, you can recall the names and sizes of the planets in our solar system. The largest planet in our solar system is Jupiter.

2. What is the atomic number of oxygen?
To determine the atomic number of oxygen, you can refer to the periodic table. Oxygen's atomic number is 8.

3. What is a metaphor?
A metaphor is a figure of speech that compares two unrelated things by stating that one thing is another. For example, "Her smile is a ray of sunshine."

4. Solve the following equation: 3x + 8 = 20.
To solve this equation, start by isolating the variable term. Subtract 8 from both sides: 3x + 8 - 8 = 20 - 8, which simplifies to 3x = 12. Then, divide both sides by 3, resulting in x = 4.

These are just a few sample questions to get you started. If you provide me with specific topics or questions related to Unit 9, I can provide more tailored review questions and explanations. Remember, the best way to prepare for your test is to review your class notes, textbooks, and any assigned materials, and practice similar problems or questions.
