Answer:

p = \frac{2}{5}

Step-by-step explanation:

3(5p - 3) = 5(p - 1)

<em><u>Try getting the x's all on one side</u></em>

15p - 9 = 5p - 5    <em>Start by adding 9 to both sides</em>

     + 9         + 9

15p = 5p + 4   <em>Then subtract 5p from both sides</em>

-5p   -5p

10p = 4     <em>Divide both sides by 10 to get p</em>

\frac{10p}{10} = \frac{4}{10}

p = \frac{4}{10} or \frac{2}{5}

maxonik [38]

9514 1404 393

Answer:

  51

Step-by-step explanation:

Let s represent the number of seats in a row. Then the number of rows is (s-9) and the total number of seats is ...

  s(s-9) = 2142

  s² -9s +4.5² = 2142 +4.5² . . . . . complete the square

  (s -4.5) = √2162.25 . . . . . . . . take the positive square root

  s = 4.5 +46.5 = 51 . . . . . . . add 4.5

The number of seats in each row is 51.

vesna_86 [32]

Answer:

74,000

Step-by-step explanation:

In the year where he got 104,000 the year before he got 6,000 less. The year before 98,000 he got 12,000 less which means that now it would just be 86,000-12,000=74,000

I think this is right but you can double check on a calculator

Hope this helped!
