So if 6 dozen cookies needs 3/4 cup of sugar, and we need to know how much sugar is needed to make 4 dozen, then find how much of 6 dozen 4 dozen is.
To do this, put it as a fraction:
4 dozen / 6 dozen, or 4/6, which is 2/3.
Since conveniently it calls for 3/4 cup of sugar, we can multiply that by 2/3, and we'll get 6/12, or 1/2.
So 1/2 cup of sugar is needed for 4 dozen cookies.
30 pints of first type and 130 pints of second type drinks must be used to make the mixture.
<em><u>Explanation</u></em>
Lets assume, the amount of first type drink is
pints.
As the total amount of the mixture is 160 pints, so the amount of second type drink
pints.
The first type is 20% pure juice, the second type is 100% pure fruit juice and the mixture is 85% pure fruit juice. So the equation will be .....

So, the amount of first type drink is 30 pints and the amount of second type drink is (160-30)pints =130 pints.
First, multiply all fractions by 2.
3x-10/8x=52
Then multiply all sides by -10.
-30x + 8x = -520
-22x = -520
Divide both sides by -22.
x=23.6363
Slope = -10
<span>pass through (2,-5)
y = mx + b
so
b = y - mx
b = -6 - (-10) (2)
b = -6 + 20
b = 14
equation
y = -10x + 14</span>
