You are making a new type of deodorant from two different mixtures the first mixture is 30% smell proof and the second mixture i

Readme [11.4K]

Answer:

600 L of 30% proof and 400 L of 80% proof is needed

Step-by-step explanation:

Let the amount of 30% smell proof be x while that of 80% smell proof is y

Then;

x + y = 1000 •••••(i)

Also;

30% of x + 80% of y = 50% of 1000

0.3x + 0.8y = 500 •••••(ii)

From i, x = 1000 - y

Put this into ii

0.3(1000-y) + 0.8y = 500

300 - 0.3y + 0.8y = 500

0.5y = 500-300

0.5y = 200

y = 200/0.5

y = 400 L

But x = 1000 - y

x = 1000 - 400 = 600 L

2(1 − x) = 9(1 + 2x) + 52(1 − x) = 9(1 + 2x) + 5

marusya05 [52]

Solving the equation $2(1-x) = 9(1 + 2x) + 5$ we get $x=-\frac{3}{5}$

Step-by-step explanation:

We need to solve the equation $2(1-x) = 9(1 + 2x) + 5$ and find value of x

Solving:

$2(1-x) = 9(1 + 2x) + 5\\2-2x=9+18x+5\\Adding\,\,-18x\,\,on\,\,both\,\,sides:\\2-2x-18x=9+5\\Adding\,\,-2\,\,on\,\,both\,\,sides\\-20x=14-2\\-20x=12\\x=\frac{12}{-20}\\x=-\frac{3}{5}$

So, solving the equation $2(1-x) = 9(1 + 2x) + 5$ we get $x=-\frac{3}{5}$
