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=\frac{-b+/- \sqrt{b^2-4ac} }{2a}
so the sum is
\frac{-b+ \sqrt{b^2-4ac} }{2a}+\frac{-b- \sqrt{b^2-4ac} }{2a}=\frac{-2b}{2a}=\frac{-b}{a}

easy peasy now

1y^2+2y-5=0
-b/a
-2/1
-2 is the sum

If y varies directly as x and y = 21 when x = 5, find x when y = 42.
Lorico [155]

Answer: 10

<u>Step-by-step explanation:</u>

varies directly means: \frac{y}{x} = k

Step 1: solve for k   ⇒  \frac{21}{5} = k

Step 2: plug in the given value and k to solve for the missing value: \frac{42}{x} = \frac{21}{5}

42(5) = 21(x)

\frac{42(5)}{21} = \frac{21(x)}{21}

2(5) = x

10  = x
