Answer:

X=8

Step-by-step explanation:

7x - 2 = 5x + 14

Subtract 5x from both sides

2x-2=14

Add 2 to each side

2x=16

Divide by 2

x=8

Answer:

8

Step-by-step explanation:

7x - 2 = 5x + 14

7x - 2 - 5x = 5x + 14 - 5x

2x -2 = 14

2x -2 + 2 = 14 + 2

2x = 16

2x /2 = 16/2

x= 8

Hope this helps ^-^

After allowing 20% discount on the marked price with 13%
saveliy_v [14]

<u>Answer:</u>

The marked price of the article is 22,600

<u>Explanation: </u>

Given, selling price of an article SP = Rs. 18080

To calculate marked price MP, the formula used is  

\mathrm{SP}=\mathrm{MP}\left(1-\frac{D \%}{100}\right)

Discount D = 20%

Substituting the given values

SP = \mathrm{MP}\left(1-\frac{20}{100}\right)

18080 = \mathrm{MP}\left(1-\frac{1}{5}\right)

18080=\mathrm{MP}\left(\frac{4}{5}\right)

\mathrm{MP}=\frac{18080 \times 5}{4}

MP = Rs. 22,600

Therefore the marked price of the article is 22,600

Anettt [7]
The first digit can be any one of the numbers 2-9 That a total of 8 numbers.

The next 6 digits can be any permutation of 6  from the numbers  0 to 9.
(10 numbers)

nPr  =  n! / r!

so here we have  10P6  = 10! / 6!  =  10*9*8*7  =  5040

So final answer  is 8 * 5040 = 40,320
