PLS HELP WILL GIVE BRAINLIEST!!! 25 PTS!!

Answer 1

$\huge \boxed {\red{\bold{Answer}}}$

x + y = 300

0.6x + 0.3y = 150

Let's use elimination. Multiply the first equation through by 0.6:

0.6x + 0.6y = 0.6*300 = 180

Now you have:

0.6x + 0.6y = 180

0.6x + 0.3y = 150

Subtract:

0.3y = 30

Divide by 0.3

y = 30 / 0.3 = 100

Since x + y = 300, that means that x = 200.

So you will need 200 ml of 60% solution and 100 ml of 30% solution.

Answer 2

Answer:

$\red{\underline{\boxed{\odot\mid{\bf{☆Answer☆}}}}}$

×+y=300

0.6x + 0.3y = 150

Let's use elimination. Multiply the first equation through by 0.6:

0.6x + 0.6y = 0.6*300 = 180

Now you have:

0.6x + 0.6y = 180

0.6x + 0.3y = 150

Subtract:

0.3y = 30

Divide by 0.3

y = 30 / 0.3 = 100

Since x + y = 300, that means that x = 200.

So you will need 200 ml of 60% solution and 100 ml of 30% solution.
