Number of pieces times weight of each piece=weight of bag 25*20=500grams per 1 bag
200kg=200000g weight of 1 bag times x bags=weight of all 500x=200000 divide both sides by 500 x=400 400 bags per day
2. factor out 6 (6)(y^2+2y-5)=0 reemmber how if we had xy=0, assume x and/or y has to be 0? assume that y^2+2y-5=0 use quadratic formula for ax^2+bx+c=0 x= so the sum is +==
