5a+c=-8a \\ 5a+c-5a=-8a-5a \\ c=-13a \\  \frac{c}{-13} = \frac{-13a}{-13}  \\  -\frac{c}{13} =a

The 9th graders are selling tickets to raise money for a class field trip. They are selling student tickets for $5 and adult tic
Marina CMI [18]

Answer:

<em>Total number of adult tickets sold = 10</em>

<em>Total Number of Students tickets sold = 30</em>

Step-by-step explanation:

Let x be the number of student tickets sold.

Let y be the number of adult tickets sold.

As per the question statement, total tickets sold are 40.

x +y =40 ...... (1)

Price of each student ticket = $5

Sales from students' tickets = Price of each students ticket \times Number of students tickets sold

Sales from student's tickets = 5 \times x

Price of each adult ticket = $9

Sales from adult's tickets = Price of each adult's ticket \times Number of adult tickets sold

Sales from student's tickets = 9 \times y

Total sales is done by students and adult tickets is $240 as per the question statement.

\Rightarrow 5x + 9y = 240 ......(2)

Solving equations (1) and (2) using elimination method:

Equation (2) - 5 \times (1) :

5x  + 9y -5x-5y = 240-200\\\Rightarrow 4y = 40\\\Rightarrow y =10

Total number of adult tickets sold = 10

Putting y=10 in equation (1):

x+10 = 40\\\Rightarrow x = 30

Total number of students tickets sold = 30

<em>Total number of adult tickets sold = 10</em>

<em>Total Number of Students tickets sold = 30</em>

13.1: Equivalent Expressions
scoundrel [369]

Distributive Property:  a ( b + c) = (a*b) + (a*c)

b)   x(x + 9) =  x*x + 9*x

               = x² + 9x    

c)  x² - 18x

     x² = x * x

  18x  = 18 *x

G C F = x

Greatest common factor in both the terms is 'x'.Take the common variable from both the terms.

x² - 18x = x*x - 18*x

            = x (x - 18)

           

Standard form.                Factored form

      x²                                     x*x

x²  +  9x                             x(x +9)

    x² - 18x                           x(x - 18)  

-x² + 10x                             x(-x + 10) = x(10 -x)

-x² - 2.75x                          -x(x + 2.75)
