You need a 75 % alcohol solution. On hand, you have a 260 mL of a 30% alcohol mixture. You also have 95 % alcohol mixture . How

user100 [1]

$30 \: percent \: alcohol \: in \: 260 \: ml \\ alcohol = 0.3 \times 26 0= 78 \: ml$

$c( \gamma ) = \frac{78 + 0.95\gamma }{260 + \gamma } \times 100$

$c( \gamma ) = 75$

$\frac{78 + 0.95\gamma }{260 + \gamma } = 0.75$

$78 + 0.95\gamma = 0.75 \gamma + 195 \\ 0.2 \gamma = 117 \\ \gamma = 585$

$we \: need \: 585 \: ml \: of \: 95% \: alcohol$

Pamela is 6 years younger than Jiri. The sum of their ages is 64. What is Jiro's age?

Viefleur [7K]

Let's use <em>j</em> to represent Jiri's age.

If Pamela is 6 years younger that Jiri, her age can be represented by <em>j - 6</em>.

Since the sum of their ages is 64, we can setup the equation j + (j - 6) = 64.

Simplifying on the left, we have 2j - 6 = 64.

Adding 6 to both sides, we have 2j = 70.

Dividing both sides by 2, we have j = 35.

So Jiri is 35 years old and Pamela is 6 years younger or 29 years old.
