1 answer:
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
+
=
=
easy peasy now
1y^2+2y-5=0
-b/a
-2/1
-2 is the sum
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

Answer:
36
Step-by-step explanation:
so we know she has sculptures and paintings, if she sold twice as many paintings as sculptures, that means that for every 2 paintings, she sold 1 sculpture, so the paintings and sculptures are on a 2:1 ratio.
we know she sold a total of 57, so we'll need to split 57 in a 2:1 ratio, we'll simply divide the whole amount of 57 by (2+1) and distribute accordingly.
