Answer:

Senior citizen ticket = $4, student ticket = $6

Step-by-step explanation:

To do this, form a system of equations where x = the cost for a senior citizen ticket and y = the cost for a student ticket.

Since 12 senior citizen tickets and 14 students tickets cost $132, you get

12x + 14y = 132.

Since 12 senior citizen tickets and 10 students tickets cost $108, you get

12x + 10y = 108.

You can subtract those two equations, so

12x + 14y = 132

-(12x + 10y = 108)

and you get

4y = 24

divide both sides by 4

y = 6

substituting into the equation 12x + 10y = 108,

12x + 10(6) = 108

12x + 60 = 108

subtract 60 from both sides

12x = 48

divide both sides by 12

x = 4

A senior citizen ticket costs $4 and a student ticket costs $6.

The sum of ages of three brothers is 79. If James I’d half as old as Brandon and Marshall is 11 years younger then Brandon how o

scZoUnD [109]

Answer:

The youngest brother is James and his age is 18 Years.

Step wise explaination:

Lets suppose,

age of James = x

age of Brandon = 2x

age of Marshall = 2x - 11

The sum of ages of three brothers = 79

now,

finding the value of x,

x + 2x + 2x - 11 = 79

or, 5x - 11 = 79

or, 5x = 79 + 11

or, 5x = 90

or, x = 90

 5

so, x = 18.

Then,

age of James = 18.

age of Brandon = 2×18 = 36.

age of Marshall = (2×18) - 11 = 25.

Therefore,

The youngest brother is James and his age is 18 Years.

<h2>Solving for the Distance between two Points</h2><h3>Answer:</h3>

$4\sqrt{5}$

<h3>Step-by-step explanation:</h3>

If you have the two points, $(x_1,y_1)$ and $(x_2,y_2)$ , the distance, $d$ , between them can be calculated by $d = \sqrt{(x_2 -x_1)^2 +(y_2 -y_1)^2}$ .

In this case, point $A$ has the coordinates $(3,0)$ and point $C$ has the coordinates $(7,-8)$ . We can finally solve for the length by finding the distance between them.

$AC = \sqrt{(7 -3)^2 +(-8 -0)^2} \\ AC = \sqrt{4^2 +(-8)^2} \\ AC = \sqrt{16 +64} \\ AC = \sqrt{80} \\ AC = \sqrt{4 \cdot 4 \cdot 5} \\ AC = 4\sqrt{5}$
