How many liters of pure water must be added to how many liters of a 25% bleach solution to make 12 liters of a 15% bleach soluti

ArbitrLikvidat [17]

Answer: 4.8 liters

Step-by-step explanation:

Let x liter of water is added with y liter of 25% beach solution.

Thus, According to the question,

x + y = 12 -------(1)

0% of x + 25 % of y = 15 % of 12

25 % of y = 15% of 12

$25 y = 15\times 12$

$y = \frac{180}{25}$

$y = \frac{36}{5}$

Put this value in equation (1),

We get,

$x + \frac{36}{5} = 12$

$x = 12-\frac{36}{5}$

$x =\frac{60-36}{5}$

$x =\frac{24}{5}$

Therefore, the quantity of water = $x =\frac{24}{5}=4.8\text{ liter}$

And, the quantity of 25% bleach solution = $y =\frac{36}{5}=7.2\text{ liter}$

Please explain I need help with all these

sergey [27]

For all of these you're trying to solve for the variable. The variable is usually a number or symbol.

11) -44+n=36
Step one would be to add 44 to both sides of the equation.

N=80

12) -36=p-91
Step one would be to add -91 to both sides of the equation.

P=55

13) X-225=671
Step one you be to add 225 to both sides of the equation. Although it may seem difficult because of the big numbers, it's the same technique.

14) 19=c-(-12)
Step one on this equation will be a little different. Because there are two negative signs (-), they turn into a plus sign. Remember, two negative signs make a positive sign.

19=c+12

Now you just subtract 12 from each side of the equation.
