Tickets for a Minor league baseball game for an adult and two children cost $21. The adult ticket is $3 more than the cost of the children's what is the price or a child and adult

The price for a child and adult ticket is $16.5

Step-by-step explanation:

Let a represent the price for an adult ticket and c the price for a child ticket

a + 2c = 21 equation (1)

The cost of the children's ticket is 2c

a = 3 + 2c equation (2)

Substitute the value of a in equation (2) into equation (1)

a + 2c = 21

3 + 2c + 2c = 21

4c = 21 - 3

4c = 18

c = 18/4 = 4.5

The price for a child ticket = $4.5

Substitute the value of c into equation 2

a = 3 + 2c

a = 3 + 2(4.5) = 3 + 9 = 12

The price for an adult ticket is $12

Price for a child and adult = $4.5 + $12 = $16.5

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
