A church luncheon made $842. Adult tickets cost $10 each and children's tickets cost $6 each. The number of children was 12 more

Orlov [11]

Solution: Let $x$ be the number of adult ticket's.

The number of child ticket $=2x+12$

We are given, that an adult ticket cost's $10 and child ticket costs $6. Also the church luncheon made $842.

Therefore,

$x \times 10 + (2x+12)6=842$

$10x+12x+72=842$

$22x=842-72$

$22x=770$

$x=\frac{770}{22}=35$

Therefore, the number of adult ticket's sold = 35

And the number of child ticket's sold = 2 x 35 + 12 = 70 + 12 = 82

Students rented buses and vans to go to a hockey game. There were 8 vans and 12 buses for 360 students.

scoundrel [369]

Answer:

A: 8v+12b=360

V= van

B= Bus

B: Each van=9

Need to ride in vans:72

Step-by-step explanation:

12 buses 24 in each bus that equals 288. 360-288=72

and if you need to know how many are in each van you divide 72 by the number of vans that would be 9 per van.

Find the coordinates of the vertices formed by the system of inequalities.

mel-nik [20]

Answer:

Step-by-step explanation:

To find the coordinates of the vertices , treat the inequalities as equations and solve them in pairs, simultaneously, that is

x + y = 9 → (1)

y - 2x = - 21 → (2) ← add 2x to both sides

y = - 21 + 2x → (3)

Substitute y = - 21 + 2x into (1)

x - 21 + 2x = 9

3x - 21 = 9 ( add 21 to both sides )

3x = 30 ( divide both sides by 3 )

x = 10

Substitute x = 10 into (3)

y = - 21 + 20 = - 1

Coordinates of vertex = (10, - 1 )

---------------------------------------------------------------------

y - 2x = - 21 → (1)

y = - 4x + 15 → (2)

Substitute y = - 4x + 15 into (1)

- 4x + 15 - 2x = - 21

- 6x + 15 = - 21 ( subtract 15 from both sides )

- 6x = - 36 ( divide both sides by - 6 )

x = 6

Substitute x = 6 into (2)

y = - 24 + 15 = - 9

Coordinates of vertex = (6, - 9 )

------------------------------------------------------------------------

x + y = 9 → (1)

y = - 4x + 15 → (2)

Substitute y = - 4x + 15 into (1)

x - 4x + 15 = 9

- 3x + 15 = 9 ( subtract 15 from both sides )

- 3x = - 6 ( divide both sides by - 3 )

x = 2

Substitute x = 2 into (2)

y = - 8 + 15 = 7

Coordinates of vertex = (2, 7 )
