System of equations <br> 3x-2y=8<br> -2x+5y=-9<br> x=<br> y=
natka813 [3]

Answer:

2y = 3x - 8

y = 3/2x - 4

Work

-2x + 5(3/2x - 4) = -9

-2x + 15/2x - 20 (+20) = -9 (+20)

-4/2x + 15/2x = 11

11/2x * (2/11) = 11 (2/11)

x = 2

3(2) - 2y = 8

6 (-6) - 2y = 8 (-6)

-2y = 2

y = - 1

final answer:

x = 2

y = -1

BiLo currently has 12-packs of Pepsi on sale for $5.55. Food Lion has a sale on 6-packs of Pepsi for $2.75. Which is the better
Gennadij [26K]
<h2>How to find the cost per can</h2>

To find the cost per can, we can divide the total cost by the number of cans.

\frac{total\ cost}{number\ of\ cans} = cost\ per\ can

<h2>Let's start with BiLo:</h2>

Total cost: $5.55

Number of cans: 12

The cost per can will be:

\frac{total\ cost}{number\ of\ cans} = \frac{5.55}{12} = 0.4625

$0.4625 per can

How about Food Lion?

<h2>Food Lion</h2>

Total cost: $2.75

Number of cans: 6

The cost per can will be:

\frac{total\ cost}{number\ of\ cans} = \frac{2.75}{6} = 0.458333....

Around $0.4583 per can

<h2>Comparing</h2>

BiLo: $0.4625

Food Lion: around $0.4583

As we can see, Food Lion has a better cost per can, as it costs less to buy each can of Pepsi.

Answer: Food Lion has a better cost per can
