Answer:
-x^2-15xy-50y^2+14y
Step-by-step explanation:
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.
Add 31 to both sides which will give you
9h = 130
25% = 0.25
124 x 0.25 = 31
31 students bought their lunch.
Part = 31
Percent = 25%
Whole = 124
