Answer:
In your equation, put 3 where x is, and -1 where y is. If you get a true statement, like -8 = -8, or 69 = 69, then (3, -1) is a solution. If you get a false statement, like 9 = 21 or 10 = 420, then (3, -1) is not a solution.
Answer:
- Keisha is right.
- No, only 1 ratio works
Step-by-step explanation:
- You want the units to be dollars / mango.
- You have 10 dollars. How many mangos can you buy and at what price. They are selling mangoes for more than a dollar each.
- The answer should be $1.25 per mango. Think of it this way:
- If the cost of a mango was $1.00 you would be able to get 10 of them. Do you agree? Since you can only get 8, they must be more than a dollar each.
- The ratio can only be written in one way. 10/8 = 1.25
