Answer:

<em>a=$10</em>

<em>c=$3</em>

Step-by-step explanation:

Step one:

given data

let adults tickets be a

and child tickets be c

so

Roy's purchase

6a+2c=66------1

Elisa's purchase

5a+4c=62-------2

Hence,  the system of equations

<em>6a+2c=66------1</em>

<em>5a+4c=62-------2</em>

<em>solving simultaneously</em>

<em>6a+2c=66------1 x2</em>

<em>5a+4c=62-------2 x1</em>

<em />

<em>   12a+4c=132</em>

<em>  -5a+4c=62</em>

<em>    7a=70</em>

<em>divide both sides by 7</em>

<em>a=$10</em>

<em />

<em>put  a=70 in 1</em>

<em>6(10)+2c=66------1</em>

<em>60+2c=66</em>

<em>2c=66-60</em>

<em>2c=6</em>

<em>c=$3</em>

nlexa [21]

Answer:

Move downward by 7 units

Move leftward by 6 units

(x,y) \to (x -6,y-7)

Step-by-step explanation:

Given

See attachment for grid

Required

The transformation from the current location to the new location

To do this, we pick two corresponding points on the current location and the new location.

We have:

A = (3,2) -- Current location

A' = (-6,-5) -- New location

First, move A downwards by 7 units.

The rule to this is:

(x,y) \to (x,y-7)

So, we have:

(3,2) \to (3,2-7)

(3,2) \to (3,-5)

Next, move the above points leftward by 6 units.

The rule to this is:

(x,y) \to (x-6,y)

So, we have:

(3,-5) \to (3-6,-5)

(3,-5) \to (-3,-5)

What is the area of the trapezoid shown below?​
Olin [163]

Answer:

78 sqr units

Step-by-step explanation:

Use the Pythagorean Theorem to help find the base opposite the two.

The base of the second parallel line is sqrt(  (15^2) - (12^2)  ) = sqrt(81) = 9

The second base = 9 + 2 = 11

Area = (b1 + b2)*h/2

h = 12

b1 = 2

b2 = 11

h = 12

Area = (11 + 2)*12/2

Area = 13 * 12/2

Area = 78 square units
