Can someone help me please this is due? ASAP
damaskus [11]

Answer:

x=12

Step-by-step explanation:

since they are supplementary they will have a sum of 180 degrees

The equation should look like this- (5x+4)+(4x+80)=180

after solving the equation- you get x=12

in order to see if that is correct you would plug in 12 where x is in our equation (5x+4)+(4x+80). which does equal 180 when 12 is plugged in

Therefore, 12 is your answer

Jefferson Middle School needs to see a 300% gain in PTO fundraiser
Ronch [10]

Given parameters:

Percentage gain = 300%

Selling cost last year = $2420

Unknown:

Selling cost this year  = ?

Solution:

To solve this problem;

     Profit percent  = \frac{Selling cost this year - Selling cost last year}{Selling cost last year} x 100

      300 = \frac{S - 2420}{2420}  x 100

      3 = \frac{S - 2420}{2420}

         S- 2420 = 7260

          S = $9680

To make a 300% gain, Jefferson Middle school needs a $9680 from fundraiser sales this year.
