Answer: 8 winter hats</h3>
Explanation:
x = number of winter hats
20-x = number of baseball hats
Dividing those quantities will get us 2/3 because of the ratio 2:3
x/(20-x) = 2/3
3x = 2(20-x)
3x = 40-2x
3x+2x = 40
5x = 40
x = 40/5
x = 8
There are 8 winter hats
And there are 20-x = 20-8 = 12 baseball hats.
The ratio 8:12 reduces to 2:3 after dividing both parts by 4. This helps confirm the answer.
Answer:
They are equal and act in opposite directions.
Step-by-step explanation:
Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.

Answer:
n = 19.89694
Step-by-step explanation:
You can work the problem using decimal numbers. There is no need to convert everything to integers. Trying to do so just gets you in trouble.
Subtract 2.2 from both sides:
-1.398 -2.200 = n/-5.53
-3.598 = n/-5.53
Now, multiply both sides by -5.53:
(-5.53)(-3.598) = n = 19.89694

The one rule that cannot be violated in algebra is that <em>you must do the same thing to both sides of the equation</em>.

Your "solution" so far has a couple of errors. The first is that you have apparently multiplied all of the numbers by 1000. Unfortunately, when you multiply a denominator by 1000, it is the same as dividing by 1000. So, you have multiplied the left side by 1000, multiplied one term on the right by 1000 and divided another term on the right by 1000. This turns the equation into something different than what you started with, and will give a wrong answer.
The second error is that you have subtracted 2200 only from the right side. This, too, will turn the equation into something different than what you started with, and will give a wrong answer.
