Given:

Selling price of a machine = 7000/-

Gross loss = 20%.

To find:

The cost and gross loss.

Solution:

Let x be the cost of machine.

According to the question,

x-20\%\text{ of }x=7000

x-\dfrac{20}{100}x=7000

x-0.2x=7000

0.8x=7000

Divide both sides by 0.8.

x=\dfrac{7000}{0.8}

x=8750

So, the cost of the machine is 8750/-.

Now,

\text{Gross Loss}=\text{Cost}-\text{Selling price}

\text{Gross Loss}=8750-7000

\text{Gross Loss}=1750

Therefore, the gross loss is 1750/-.

makkiz [27]
So if there is 7 people and shakes the hand of everyone once it would be  6 shakes for one person to shake all the 7 people.6 because himself is counted as one.
So if we multiply 6x7 we would have our answer which in this case is 42 
42 handshakes in total from everybody.

90=3(x+8)+2x-4 what is x
Lilit [14]

Answer:

x = 14

Step-by-step explanation:

Solve for x:

90 = -4 + 2 x + 3 (x + 8)

3 (x + 8) = 3 x + 24:

90 = 3 x + 24 + 2 x - 4

Grouping like terms, 3 x + 2 x - 4 + 24 = (2 x + 3 x) + (-4 + 24):

90 = (2 x + 3 x) + (-4 + 24)

2 x + 3 x = 5 x:

90 = 5 x + (-4 + 24)

24 - 4 = 20:

90 = 5 x + 20

90 = 5 x + 20 is equivalent to 5 x + 20 = 90:

5 x + 20 = 90

Subtract 20 from both sides:

5 x + (20 - 20) = 90 - 20

20 - 20 = 0:

5 x = 90 - 20

90 - 20 = 70:

5 x = 70

Divide both sides of 5 x = 70 by 5:

(5 x)/5 = 70/5

5/5 = 1:

x = 70/5

The gcd of 70 and 5 is 5, so 70/5 = (5×14)/(5×1) = 5/5×14 = 14:

Answer:  x = 14
