<em>Greetings from Brasil...</em>
X = 2 liter container
Y = 3 liter container
the total of containers are:
X + Y = 400
the capacity of the containers is
2X + 3Y = 1100
Assembling the equation system
2X + 3Y = 1100
X + Y = 400 x(-2)
2X + 3Y = 1100
<u>-2X -2Y = - 800 </u>
<h3>Y = 300</h3>
X + Y = 400 so
X + 300 = 400
X = 400 - 300
<h3>X = 100</h3>

<em>Observe que:</em>
<em>1 vasilha de 2L = 1 × 2 = 2L</em>
<em>2 vasilhas de 2L = 2 × 2 = 4L</em>
<em>3 vasilhas de 2L = 3 × 2 = 6L</em>
<em>X vasilhas de 2L = X × 2 = 2X litros</em>
<em>.....</em>
<em>1 vasilha de 3L = 1 × 3 = 2L</em>
<em>2 vasilhas de 3L = 2 × 3 = 4L</em>
<em>3 vasilhas de 3L = 3 × 3 = 6L</em>
<em>X vasilhas de 3L = X × 3 = 3X litros</em>
<em>Logo 2X + 3Y = 1100</em>
<em>Existem X e Y vasilhas que num total sao 400, logo</em>
<em>X + Y = 400</em>
Answer:
180% ; 5
Step-by-step explanation:
Purchase price per coat = 55
Sales price per coat = 99
% of purchase price is sales price :
X% * 55 = 99
(x / 100) * 55 = 99
0.01x * 55 = 99
0.55x = 99
x = 99 / 0.55
x = 180
180% of purchase price
B.)
180% * 45 = 81 per jacket
Number of jackets to sell to make atleast $390 in sales
$390 / $81 = 4.8
Hence, 5 jackets
Answer:7/23
Step-by-step explanation:
Answer:
Grapes 12 lbs
Apples 20 lbs
Oranges 6 lbs
Cantaloupe 15 lbs
Peaches 15 lbs.
Step-by-step explanation:
Sammy has bought 12 lbs of Grapes.
Now, weight ration of Apples to Grapes is 5 : 3
Therefore, he bought Apples of lbs
The wight ration of Grapes to Oranges is 4 : 2
Therefore, he bought Oranges of lbs
Again, the weight ratio of Cantaloupe to Apples is 3 : 4
Therefore, he bought Cantaloupe of lbs
Finally the weight ratio of Oranges to Peaches is 2 : 5
Therefore, he bought Peaches of lbs
