Personally I used desmos in algebra it gives you the visual representation x=
X^2 + 9x -10 = (x -1)(x +10) = (x +(-1)) (x + 10)
p = -1 and q = 10
answer is A.
Karen = x
bill = 2x - 9
total = x + 2x - 9 = 3x - 9
It totals out to 4. I/3 plus 2/3 would equal 1 whole number, then add 1+2+1, you will get 4!
If 0.75 cups = 20 cookies
0.375 cups = 10 cookies
1.875 cups = 50 cookies
