Step-by-step explanation: To understand the commutative, let's look at the following problem.

2 + 3 = 3 + 2

The problem shown above demonstrates the commutative property of addition. In other words, the commutative property of addition says that changing the order of the addends does not change the sum.

For example here, we can easily see that the sum of 2 + 3 gives us 5 is equal to the sum of 3 + 2 which is also 5.

In more general terms, the commutative property of addition can be written as a + b = b + a where a and b are each variables that can represent any number.

Which of the following best describes an irrational number?
Furkat [3]

Answer:

Option D is correct.

D- A number that cannot be expressed as a fraction, , where p and q are integers

Step-by-step explanation:

Irrational number:

An irrational number can not be expressed as a fraction or ratio of  integers, like \frac{p}{q} where p and q are integers

And also it can not be expressed as terminating decimal or repeating decimal

Example of the irrational number is given below.

\sqrt{8}= 2.82842

\pi = 3.14285..

\sqrt{3}= 2.82842

Therefore option D (A number that cannot be expressed as a fraction, , where p and q are integers) is correct .

I am Lyosha [343]

The statement which describes what the equation tells is; The number of customers they have prior/before the review is; 500 customers.

  • The number of customers they have 2 months after the review is; 222.22 customers.

<h3>Exponential functions</h3>

According to the given function;

  • The intercept of the function represents the number of customers the restaurant has prior to the review.

This means the number of customers they have prior/before the review (at m=0) is; 500 customers.

Additionally, after 2 months of the review;

  • C = 500 × (2/3)^2

  • C = 500 × 0.44

C = 222.22 customers

How many solutions does the equation 5x + 3x − 4 = 10 have? Zero One Two Infinitely many (please explain)
Ymorist [56]
Here are the steps to solve:
1. Combine 5x and 3x Now you have 8x -4 = 10
2. Get x alone by adding 4 (But be fair so you have to do it on both sides)
Now you have 8x = 14
3. Divide both sides by 8 

x = 8/14 (Which is 0.57142857)
