Formula for the terms shows that it starts at 6 and decreases by 4
6, 2, -2. -6, ...

4th term is -6
you can also just put in n = 4 for the 4th term and solve for it.

To set up a venn diagram, you need the following details below

  • Set A = ( 3, 6, 9, 12, 15 )
  • Set B = ( 1, 3, 5, 7, 9. 11, 13, 15 )
  • A∩B = ( 3, 9 )
  • U = (1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16)

<h3>Meaning of a set and a venn diagram</h3>

A set is the orderly collection of elements, material, numbers and items that satisfy a condition.

A set could be finite or infinite.

A venn diagram is a diagramatic representation of a set using circles. it mostly represents a finite set.

In conclusion, you can use the details above to draw your venn diagram.

-1.398 = 2.2 + n/-5.53<br> Does this look good so far? <br> -1398 = 2200 + n/5530 - 2200
insens350 [35]

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.
