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

How do i solve <br> −4(m+6)=−8

geniusboy [140]

Answer: -4 (m + 6) = -8

We can use the distributive property for the first half of the equation.

-4 × m = -4m

-4 × 6 = -24

-4m - 24 = -8

Now we add 24 on bothe side sof the equation to get -4m by itself.

-4m - 24 + 24 = -8 + 24

Now we get -4m = 16

Divide -4 on both sides to get m by itself

-4m/-4 = 16/-4

Simplify and we get m = -4

{1, 4, 9, 4, 10, 8, 42} What is the best measure of center for this data set?

1, 4, 9, 4, 10, 8, 42

Put this into order.

1, 4, 4, 8, 10, 42

It would most definitely not be the mode, because there is an outlier, and it wouldn't be the median, because once again, there is an outlier.

So, that leaves you with the mean.

The mean would measure this the best because it'll represent it the best. It is also the only one that'll fully make sense.

So, your answer is : The mean.

~Hope I helped!~
