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 <em>p </em>standing for <em>part </em>and <em>w</em> standing for the <em>whole</em>)

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!

What is 1/2(7x-6)=6x-10
erastova [34]

Answer:

Step-by-step explanation:

1/2(7x - 6) = 6x - 10

7/2x - 3 = 6x - 10 .....multiply by 2

7x - 6 = 12x - 20

-6 + 20 = 12x - 7x

14 = 5x

14/5 = x  <===
