Answer:

Step-by-step explanation:

let the number be n , then the number divided by 3 is $\frac{n}{3}$ and decreased by 5

$\frac{n}{3}$ - 5 = 6 ( add 5 to both sides )

$\frac{n}{3}$ = 11 ( multiply both sides by 3 )

n = 33

The number is 33

Nonamiya [84]

Answer:

4.9%

Step-by-step explanation:

6600 * 107/100 = 66*107 = 7062.

3500 * 101/100 = 35x101 = 3535

7062+3535=10597. Original worth: 10100

10597-10100 = 497

497/10100 = 0.0492079208, or 4.92%, rounds to 4.9%

Rami bought a house on 1st January 2015. In2015 the house increased in value by 15%. In 2016 the house decreased in value by 8%.

shepuryov [24]

Answer:

The value of the house on 1st January 2015 was of $650,000.

Step-by-step explanation:

Decimal multipliers:

For a increase of a%, the decimal multiplier is given by $\frac{100+a}{100}$

For a decrease of a%, the decimal multiplier is given by $\frac{100-a}{100}$

Rami bought a house on 1st January 2015.

For a value of x.

In 2015 the house increased in value by 15%.

This means that x is multiplied by $\frac{100+15}{100} = \frac{115}{100} = 1.15$

In 2016 the house decreased in value by 8%.

This means that 1.15 times x is multiplied by $\frac{100-8}{100} = \frac{92}{100} = 0.92$

On 1st January 2017 the value of the house was $687700.

The value of these multiplications is 687700.

What was the value of the house on 1st January 2015?

This is x, so:

$x*1.15*0.92 = 687700$

$x = \frac{687700}{1.15*0.92}$

$x = 650000$

The value of the house on 1st January 2015 was of $650,000.
