Answer:

3. w=P/2-L

Step-by-step explanation:

Given formula:

P=2(l + w)

Solving for w:

P=2(l + w)
P/2 = 2(l + w)/2
P/2 = l + w
P/2 - l = l + w - l
P/2 - l = w
w = P/2 - l

Correct answer choice is:

3. w=P/2-L

10% of the passengers on a fly with us airlines flight are in first class. If there are 40 passengers in first class, how many t

MissTica

Answer:

400 passengers

Step-by-step explanation:

To solve the problem, a proportion would be best!

First, let's set up the left side of the proportion. Percents, when used in parts, are always part of 100%, making 100% a whole. We'll use both 10% and 100% as our first fraction, which should look something like this:

$\frac{10p}{100w}$ (with p standing for part and w standing for the whole)

Next, let's set up the right side of our proportion. We'll use the 40 for our part and x for our whole since that is the number we are solving for. The proportion should now look like this:

$\frac{10p}{100w} = \frac{40p}{x}$

To solve, just cross multiply and divide! Multiply 40 by 100 to give you 4,000. Next, divide 4,000 by the remaining 10 to give you a final answer of 400. If 40 passengers on the flight are in first class, then there are 400 total passengers. Hope this helps!
