Since this is a never ending number, (irrational), you may estimate it. Examples: 4777/1000 477/100 47/10

Answer:

\frac{43}{9}

Step-by-step explanation:

We require 2 equations with the repeating 7 placed after the decimal point.

let x = 4.7777... → (1)

Multiply both sides by 10

10x = 47.7777.... → (2)

Subtract (1) from (2) thus eliminating the repeating 7

9x = 43 ( divide both sides by 9 )

x = \frac{43}{9}

How many times larger than 2x10^3 is 6x10^6?
Zielflug [23.3K]

Answer: 5,998,000

Step-by-step explanation:

2x10^3= 2,000

6x10^6= 6,000,000

In translation, Use 1 x The Initial SIG FIGS, or first numbers. 10x10 is 100, and notice how 10 and 10 have 2 zeros, so 1x1 = 1 +00 is a way to construct the number.

In this case, the 10^x, the x can represent the number of zeros after our first value.

So, 6 + six zeros, or 6,000,000

and, 2 + 3 zeros, or 2,000

To find the difference, subtract the numbers from eachother and extract the absolute value, (meaning the final answer won't be negative).

So, 6,000,000 - 2,000 = 5,998,000, which is the answer to the prompt!

Hope this Helped!

Solve the equation<br> 2/3x - 1/9x + 5 = 20
Drupady [299]

Step-by-step explanation:

2/3 x - 1/9 x + 5 = 20

6/9 x - 1/9 x = 15

5/9 x = 15

x = 15 * (9/5) = 27.
