Is -9.2222 a irrational number? Or rational? Im so confused
finlep [7]

Answer:

  rational

Step-by-step explanation:

Any number that can be written with a finite number of digits is rational. The given number is rational. (It has 5 digits.)

__

Any repeating decimal is rational.

If this were -9.2222..., it would be -9 2/9 = -83/9, also a rational number.

_____

A number is irrational if it cannot be represented exactly as a decimal or repeating decimal. That is, its decimal fraction part continues forever without repeating.

What value of n makes the statement true? <br> 6xn · 4x2 = 24x6
tensa zangetsu [6.8K]

The answer is: n=4

The explanation of this exercise is shown below:

1. You have the following expression given in the problem above:

(6x^{n})(4x^{2})=24x^{6}

2. By the exponents properties, when you multiply powers with the same base, you must sum the exponents. In this case the base is x, therefore, you must sum the exponents.

3. The result of the sum is 6, therefore, n must be 4:

(6x^{4})(4x^{2})=24x^{6}

Part A
OLEGan [10]

Part A: The algebraic equation for the situation is 2x - 3 = 5

Part B:  Bob has 4 brand new music CD's

Step-by-step explanation:

Translate the situation into an algebraic equation:

  • Ann has 5 brand new music CD’s, which is 3 less than twice the amount that Bob (x) has
  • Find the value of x (the number of brand new CD's Bob has)

Part A:

∵ Bob has x brand new CD's

∵ Ann has 5 brand new music CD’s, which is 3 less than twice

  the amount that Bob has

- That means multiply x by 2 and then subtract 3 from the product

  and equate the answer by 5

∵ Twice x 2x

∵ 3 less than twice x = 2x - 3

∴ 2x - 3 = 5

The algebraic equation for the situation is 2x - 3 = 5

Part B:

Let us solve the equation to find the value of x

∵ 2x - 3 = 5

- Add 3 to both sides

∴ 2x = 8

- Divide both sides by 2

∴ x = 4

Bob has 4 brand new music CD's
