Answer:

$39.95

Step-by-step explanation:

Thus, a product that normally costs $799 with a 5 percent discount will cost you $759.05, and you saved $39.95. You can also calculate how much you save by simply moving the period in 5.00 percent two spaces to the left, and then multiply the result by $799 as follows: $799 x . 05 = $39.95 savings.

The denominator of a fraction is 4 more than the numerator if both are decreased by 3 the simplified result is 6/7 find original

Hitman42 [59]

<u>Answer:</u>

The denominator of a fraction is 4 more than the numerator. The original fraction is $\frac{27}{31}$

<u>Solution:</u>

Given that

Denominator of fraction is 4 more than the numerator.

Let’s say numerator of fraction be represented by variable x.

So denominator of a faction as it is four more that numerator will be x + 4

Also given if both decreased by three than simplified result is $\frac{6}{7}$

$=>\frac{(x-3)}{((x+4)-3)}=\frac{6}{7}$

Solving above equation for x

=> 7(x – 3 ) = 6 ( x + 1 )

=> 7x – 21 = 6x + 6

=> 7x – 6x = 6 + 21

=> x = 27

Numerator of fraction = x = 27

Denominator of fraction = x + 4 = 27 + 4 = 31

$\text {required fraction}=\frac{\text {numerator}}{\text {denominator}}$

$= \frac{27}{31}$

Hence the original fraction is $\frac{27}{31}$

Marrrta [24]

Answer:

$4\frac{3}{4}ft$

Given that Malcolm started with $5\frac{3}{4}ft$ of board, then cut off a section that was 1 foot in length, you can subtract the length of the section from the total amount he started with:

$5\frac{3}{4}ft$ - 1 = $4\frac{3}{4}ft$
