Answer: x=-5

Step-by-step explanation:

You need to find the value of the variable "x".

Solve for "x":

Subtract \frac{5}{6}x from both sides of the equation:

\frac{2}{3}x-\frac{1}{2}-\frac{5}{6}x}=\frac{1}{3}+\frac{5}{6}x\\\\-\frac{1}{6}x-\frac{1}{2} =\frac{1}{3}

Add  \frac{1}{2}  to both sides of the equation:

-\frac{1}{6}x-\frac{1}{2}+\frac{1}{2} =\frac{1}{3}+\frac{1}{2}\\\\-\frac{1}{6}x=\frac{5}{6}

Multiply both sides of the equation by -6:

(-\frac{1}{6}x)(-6)=(\frac{5}{6})(-6)\\\\x=-5

1/2 of the people in the clinic are men, 1/3 are elderly, how many people are not elderly or men?
Nostrana [21]

1/6 of the people are not elderly or men

<h3>How to determine the proportion?</h3>

The given parameters are:

Men = 1/2

Elderly = 1/3

The number of people that are not elderly or men are:

People = 1 - Men - Elderly

So, we have:

People = 1 - 1/2 - 1/3

Evaluate

People = 1/6

Hence, 1/6 of the people are not elderly or men

A boiler has five identical relief valves. the probability that any particular valve will open on demand is .95. assuming indepe
Marysya12 [62]
To calculate P(at least one valve opens), we can find 1 - p(no valves open).
This is equal to 1 - (0.05)^5, or 0.9999996875. 
P(at least one valve fails to open) is equal to 1 - p(all valves open and none fail). This is 1 - (0.95)^5, or 0.2262190625.

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
