LITTERLY HELP ME PLEASEE..... 2/x-4x/2x-3=-2<br> PLEASEE I INSERTED A PIC

Stels [109]

Answer:

x = -3

Step-by-step explanation:

Given expression is,

$\frac{2}{x}- \frac{4x}{2x-3}=-2$

$\frac{2(2x-3)}{x(2x-3)}-\frac{4x(x)}{x(2x-3)}=-2$

$\frac{2(2x-3)-4x^{2} }{x(2x-3)}=-2$

(4x - 6) - 4x² = -2x(2x - 3)

4x - 6 - 4x² = -4x² + 6x

4x - 6 = 6x

6x - 4x = -6

2x = -6

x = -3

how many ounces of pure water must be added to 50 ounces of a 15% saline solution to make a saline solution that is 10% salt

anygoal [31]

50 ounces of 15% saline solution contains 0.15*50 = 7.5 ounces of salt.

Let x be the amount of pure water you add to this solution. Then you end up with (x + 50) ounces of this new solution. The amount of salt stays the same.

You want the new solution to have a concentration of 10%. This means you need

7.5 / (x + 50) = 0.1

==> 7.5 = 0.1(x + 50)

==> 7.5 = 0.1x + 5

==> 2.5 = 0.1x

==> 2.5/0.1 = 0.1x/0.1

==> x = 25
