Answer:

They bought 0 ticket of closest section and 7 tickets of other section

Step-by-step explanation:

- Callie and Madison went to buy concert tickets for themselves and

  their five friends

- That mean they are 7

- Tickets for the closest section were $45 each

- Tickets for other section were $30 each

- They  ended up spending a total of $210

- Assume that they buy x tickets for closest section and y tickets for

 the other section

∵ They want 7 tickets

∴ x + y = 7 ⇒ (1)

∵ The cost of the closest section ticket was $45

∵ The cost of the other section ticket was $30

∵ They spent $210 on them

∴ 45x + 30y = 210

- All terms have common factor 15, then divide them by 15

∴ 3x + 2y = 14 ⇒ (2)

* Now we have a system of equations to solve

- Multiply equation (1) by -2 to eliminate y

∴ -2x - 2y = -14 ⇒ (3)

- Add equations (2) and (3)

∴ x = 0

- substitute the value of x in equation (1) to find y

∴ 0 + y = 7

∴ y = 7

∵ x represents the number of tickets of the closest section and y

  represents the number of tickets in the other section

∴ They bought 0 ticket of closest section and 7 tickets of other

   section

G(x) = -3/2x-9, if G(x) = -48, find x
Svetlanka [38]

Answer:

x=26

Step-by-step explanation:

first rewrite the problem since u know that G(x)=-48

-48=-3/2x-9

second you want to add the 9 to -48 which gives u -39

-39=-3/2x

third you want to times the reciprocal so it would be

-2/3 times -39/1

u can cross out the negatives and turn them into a positive

fourth you can cross cancel 3 and 39 which now the problem looks like this

2/1 times 13/1

which you would times 2 and 13 which your answer would be

26

Robin has triple as many marbles Amy. Sam has 15 more marbles than robin. Together they all have 99 marbles. How many marbles do
tigry1 [53]
Let:     x be Amy's marbles
         3x be Robin's marbles
   15+3x be Sam's marbles
x+3x+15+3x=99
          7x+15=99
                7x=99-15 (transfer 15 to the right side of the equation, then minus)
             7x/7=84/7 (divide both sides of the equation by 7)
                  x=12
Now substitute:
                             x = 12 (Amy's)
                3x = 3*12 = 36 (Robin's)
   15+3x  = 15+3*12 =  51 (Sam's)
               12+36+51 = 99
Therefore, Amy has 12 marbles, Robin has 36 marbles and Sam has 51 marbles.
