I need help with this one.
Mandarinka [93]

Answer:

T_{n} = \frac{1}{5} T_{n-1} with T₁ = 5000

Step-by-step explanation:

There is a common ratio r between consecutive terms in the sequence, that is

r = \frac{1000}{5000} = \frac{200}{1000} = \frac{40}{200} = \frac{1}{5}

This indicates the sequence is geometric with recursive rule

T_{n} = r T_{n-1}

Here tr = \frac{1}{5} , thus

T_{n} = \frac{1}{5} T_{n-1} , T₁ = 5000

Ik what it is just helping out others 1+1
antiseptic1488 [7]

The question is asking what will we get if we add 1+1.

Let us use an example to understand this.

Example:

Suppose Amy has 1 ice cream and her brother Ruth has also got one ice cream.

Now if they both finished their ice creams, how many total ice creams were finished.

So we see that 1 and 1 add up to give two ice creams and so two ice creams are finished by them both.

Applying this to our question adding 1 and 1 gives us 2.

Answer : 1+1 =2

MA_775_DIABLO [31]

Answer:

x = -50/9    

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

Step-by-step explanation:

<u>Step 1: Define equation</u>

3x - 8 - 12x = 42

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Combine like terms:                    -9x - 8 = 42
  2. Isolate <em>x</em> term:                              -9x = 50
  3. Isolate <em>x</em>:                                        x = -50/9
