1 answer:

4 0

Start at (0,2) and draw a dot. Then, go up 2 units, and right 5 times. Draw a dot. Now connect the 2 dots and extend the line.

Now, it's graphed! :)

2/25 *5 as a fraction

bulgar [2K]

For this case we must rewrite the following expression as a fraction:

$\frac {2}{25} * 5$

So, we have:

$\frac{2*5}{25} =\\\frac{10}{25} =$

We divide numerator and denominator by 5:

$\frac {2} {5}$

Thus, the simplified expression is:

$\frac{2} {5}$

Answer:

$\frac {2} {5}$

Tank A contains a mixture of 10 gallons water and 5 gallons pure alcohol. Tank B has 12 gallons water and 3 gallons alcohol. How

12345 [234]

We know that
The mixture in Tank A is 5/(5+10) = 1/3 pure alcohol.
The mixture in Tank B is 3/(3+12) = 1/5 pure alcohol.
We want to combine these to make a mixture that is 25% = 1/4 pure alcohol.
Let
x------------------> the volume in gallons of solution taken from Tank A.
y------------------>the volume in gallons of solution taken from Tank B
Then
the volume taken from Tank B will be y=(8 -x)
remember that we are making a total of 8 gallons of solutions.

The alcohol content of the mixture is(1/3)x +(1/5)(8 -x) = (1/4)*85x + 3(8 -x) = 30 ----------> 5x+24-3x=30----------> 5x-3x=30-24
2x = 6 ----------------> x=3
y=8-x--------> y=8-3-----> y=5

the answer is
3 gallons should be taken from Tank A;
5 gallons should be taken from Tank B
