Answer:
4 each of red and green binders.
Step-by-step explanation:
Given: Price of each red binder is $2.25.
Price of each green binder is $3.24.
Total Jackie paid is $21.96.
Lets assume the number of red binder bought be "x".
∴ Total amount paid for red binder= 
⇒ Total amount paid for red binder= 
Now, finding the amount paid for green binder.
As we know the total amount paid by Jackie is $21.96 and she bought same number for each binder.
Jackie paid for x number of green binder= 
Next, we can write an equation on total amount paid for Green binder to find value of x.
∴ 
Solving the equation.
Adding both side by \$ 2.25x
⇒ 
⇒ 
cross multiplying both side.
⇒ 
∴ x= 4
Hence, Jackie bought 4 each of red and green binders as she bought same number of each binders.

Answer:
13.50 ≤ 1.20x + 3
Step-by-step explanation:
Janie is saving for a CD, which costs $13.50. Janie can earn more than that amount, but needs to save at least that much to buy the CD. So, the amount of money she has needs to be greater than or equal to $13.50.
Next, Janie has $3 to begin with. Although she already has some money to start with, that is still not enough to purchase her CD. To earn money, she will do chores ($1.20 per chore). We do not know the amount of chores she will do, so we can mark that as variable x.
If we put that all together, we will get 13.50 ≤ 1.20x + 3. If you solver this equation, you can solve how many chores she will have to do, but that is not part of the question!!
Now, for the graph. A closed dot represents if it is not only greater or less than, but it also has a possibility to be equal as well. So, this dot will be closed. As I said before, the amount of money she has all together has to be greater than or equal to $13.50. Starting from the dot, you will draw the arrow to the right, which symbolizes that all of these numbers are the solution.
I hope this helped you! Have a great rest of your day.
Answer:
-4x+ 1/10
Step-by-step explanation:
−1/2x−1/5−5x+3/10+3/2x
Combine like terms
-1/2x -5x + 3/2x -1/5 + 3/10
Get a common denominator for each group
-1/2x -10/2x + 3/2x -2/10 + 3/10
-8x/2 + 1/10
Simplify
-4x + 1/10
-4x + 1/10
