40*5%= 2
0.07x+0.02y=2
x+y=40
7x+2y=200
2x+2y=80
5x=120
x= 24
7x+2y=200
7x+7y= 280
5y=80
y=16
A: 24gallons of 7%milk
16 gallons of 2% milk
If I am reading the question correctly it would come out to -6x+42 First do all the addition and squaring, then factor in that negative. You come out to -2x^3 +2x^3-4x-2x+25+5+9+3. The x^3's cancel, the -x's add to -6x, then all that other adds to 42.
Sum means add.
So, we'd need to add
4 5/6 + 3 5/6
5/6 + 5/6 = 10/6, or 1 4/6, or 1 2/3.
4 + 3 = 7
7 + 1 =8
8 2/3 is your answer.
Glad I could help, and good luck!
