a dairy needs 306 gallon of milk containing 6% butterfat. how much gallons each of milk containing 7% butterfat and milk contain

Andreyy89

$306 \times 6\%=306 \times 0.06=18.36$
306 gallons of milk containing 6% butterfat contain 18.36 gallons of butterfat.

x - the number of gallons of 7% milk
y - the number of gallons of 4% milk

$x+y=306 \\
7\%x + 4\%y=18.36 \\ \\
x+y=306 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ |\times (-4) \\
0.07x+0.04y=18.36 \ \ \ \ |\times 100 \\ \\
-4x-4y=-1224 \\
\underline{7x+4y=1836 \ \ \ \ \ \ } \\
7x-4x=1836-1224 \\
3x=612 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ |\div 3 \\
x=204 \\ \\
x+y=306 \\
204+y=306 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ |-204 \\
y=102$

204 gallons of 7% milk and 102 gallons of 4% milk should be used.

The age of a boy is twice that of his sister. five years ago the boy was 3 times the age of his sister. How old is the boy

joja [24]

Answer:

<h2>20 years old.</h2>

Solution,

Let the age of sister be X

Let the age of boy be 2x

Now,

Five years ago,

 $3(x - 5) = 2x - 5 \\ or \: 3x - 15 = 2x - 5 \\ or \: 3x - 2x = - 5 + 15 \\ x = 10$ 

Again,

Replacing value,

 $age \: of \: boy = 2x \\ \: \: \: \: \: \: \: \: \: \: \: \: \: = 2 \times 10 \\ \: \: \: \: \: \: \: \: \: \: \: = 20$ 

hope this helps..

Good luck on your assignment..
