Equation:
500-30x=130+20x
Since you want to find when they are the same, you put an equal sign. Also, since one is gaining and the other is losing, you have an addition and subtraction sign.
Solution:
370= 50x
x=7.4
Answer:
After 7.4 years, the clubs will have the same members, which is 278 members.

Answer:

5 1/3

Step-by-step explanation:

<h2>Lesson: Adding or Sutracting Fractions</h2>

<em>Convert mixed number to improper fraction.</em>

<em>3 5/6=23/6</em>

<em>23/6+3/2</em>

<em>23/6+9/6</em>

<em>Denominators are equal, and it should be combine the. fractions.</em>

<em>23+9/6</em>

<em>Add the numbers from left to right.</em>

<em>23+9=32</em>

<em>32/6</em>

<em>Make sure to cancel by the common factor of 2.</em>

<em>16/3</em>

<em>Convert improper fractions into the mixed number.</em>

<em>16/3=5 1/3</em>

<em>5 1/3 is the correct answer.</em>

<em>I hope this helps you, and have a wonderful day!</em>

Select all of the factors of x3 + 5x2 + 2x – 8.
gladu [14]

The factors of this polynomial would be (x + 4)(x + 2)(x - 1).


To find these, you first have to start with long division to find the first factor. If you use x + 4 it would look like this.


\frac{x^{3} + 5x^{2} + 2x - 8}{x + 4} = x^{2} + x - 2


Now we are left with only x^{2} + x - 2. We can factor this by looking for numbers that multiply to the last number and add to the middle number. 2 and -2 multiply to -2 and add to 1. Therefore, we'll use those in parenthesis in their place.


(x + 4)(x + 2)(x - 1)

1. The additive identity is 0. This is because adding 0 to anything leads to the same value. Example: 0+3 = 3.

2. An equation is where you have two expressions separated by an equal sign. In your case it would be "a mathematical sentence whose verb is 'equal' (=)"

3. The multiplicative identity is 1. Multiply 1 with any number and the result is that same number. Example: 1*7 = 7.

4. An open sentence is an equation that contains one or more variables. An example would be x+2 = 4. The reason why we call it open is because the true or false nature of the sentence is up in the air until we know what x is. If we knew that x = 3 for instance, then x+2 = 4 would be false since 3+2 = 4 is false. If we nailed down what x was then it would go from open to closed.

5. The symmetric property is that if a = b then b = a. Think of a mirror how the image reverses.
