Answer:

360 Adults

Step-by-step explanation:

Let's represent the number of Adults with x.

Number of children = 2 * x = 2x.

The total amount collected for both children and adults = 1080.

Therefore, to know the number for adults we use the expression:

x + 2x = 1080

3x = 1080

Divide through by 3

x = 1080/ 3

x = 360.

Therefore, there are 360 adults.

Children would 2x

= 2*360

=720

F(x)=3x<br>g(x)=-x+1<br>(f×g)(7)
likoan [24]
F(x) = 3x
F(7) = 21

g(x) = -x + 1
g(7) = -7 + 1 = -6

(F x g)(7) = (21) (-6)  =  -126

Connor needs to replace the edging on a square rug. If the rug has a area of 25 m2, what length of edging does he need?
exis [7]
For this problem you are going to want to take 25 and find the square root. You get 5
This is the length of one side
Since it is a square and squares have 4 sides you will have to multiply 4 by 5
This gives you 20
Your answer is:

Which ordered pair is a solution of the equation 2x − y = 9?
gladu [14]

The correct answer is:    [C]:    " (5, 1) ".

__________________

Explanation:

__________________

Choice:  [C]:  " x = 5 " ;  " y = 1 " ;

Note:  Given the equation:  " 2x - y = 9 " .

  → Plug in " 5 " for "x" , and " 1  for " y " ;

to get:   " [2 * 5]  -  [1]   =   10  -  1  =  " 9 " ;  and:  " 9  =  9 " .

So,  Choice:  [C]:  " (5, 1) "  — is the CORRECT ANSWER.

__________________

Let us consider the "other answer choices" ; as follows:

__________________

Choice:  [A]:  "x = - 4 " , "y = 1" ;  Plug in these values for the given equation:

→  " 2x - y = 9 " ;

→  " (2 * -4) - (5) = - 8 - 5 =  " - 13 "  ;  and:  " - 13 ≠ 9 " .

→  So:  Answer choice:  [A]:  is INCORRECT.

__________________

Choice [B]:  "x = -2" , "y = 5" ;  Plug in these values for the given equation:

  "2x - y = 9 " ;

→  " (2 * -2) - (5) = -4 - 5 = -9 ;  and:  " -9 ≠ 9 " .

→  So:  Answer choice:  [B]:  is INCORRECT.

__________________

Choice:  [D]:  "x = 6 " , "y = - 3" ;  Plug in these values for the given equation:

  "2x - y = 9 " ;

→  " (2 * 6) - ( -3) =  12 - (-3)  =  12 + 3  = " 15 " ;  and:  " 15 ≠ 9 " .

→  So:  Answer choice:  [D]:  is INCORRECT.

__________________

     →  The correct answer is:    [C]:    " (5, 1) " .
