Prove algebraically that 0.5 recurring = 5/9

Mathematics
1 answer:
weeeeeb [17]2 years ago
5 0

Answer:

see explanation

Step-by-step explanation:

We require 2 equations with the recurring part after the decimal point.

Let x = 0.555..... → (1)

Multiply both sides by 10, then

10x = 5.555..... → (2)

Subtract (1) from (2) thus eliminating the recurring decimal

(10x - x) = (5.5555 - 0.5555 ), that is

9x = 5 ( divide both sides by 9 )

x = \frac{5}{9}

What number divided by 2 3 4 5 6 has a remainder of 1 but when divided by 7 has no remainder?
Afina-wow [57]
301

We could start by finding the lowest common multiple of 2, 3, 4, 5, and 6, which is 60. Then, we can consider the next few multiples: 120, 180, 240, 300...

However, because we need a remainder of 1 when our number is divided by each of these numbers (2,3,4,5,6), we want to go one above each of these multiples. So we're talking about 61, 121, 181, 241, 301... Those are the numbers that will satisfy the "remainder of 1" part of the question.

Now, we need to find out which one satisfies the other part of the question, which just requires dividing each of these numbers by 7 to see which is divisible by 7 (in other words, which one gives us a remainder of zero when we divide by 7). 

301 does it. 301/7 = 43. So 301 is a multiple of 7 and therefore will yield no remainder when divided by 7.

Hope this all makes sense.

The balance of an investment account is $308.32
Nady [450]

The balance was $4400.25 before 4 years.

<h3>What is an Equation?</h3>

An equation is a mathematical statement formed when two expressions are equated using an equal sign.

The equations are useful in the determination of unknown parameters.

The equations are of various types, such as Trigonometric equations, and quadratic equations.

The balance of an investment account is $308.32

Let the balance 4 years ago was $x

Then the balance today is represented by x + 308.32

The current balance is $4708.57

The expressions can be equated to get the value of the balance 4 years ago.

x + 308.32 = 4708.57

x = 4708.57 - 308.32

x = $4400.25

The balance 4 years ago was $4400.25
