6 children and 2 adults are going to the circus. Children tickets are on sale,half price of adult tickets totaling $54. How much

Anon25 [30]

Answer:

Price of 1 adult ticket is <u>$10.8</u> and Price of 1 children ticket is <u>$5.4</u>.

Step-by-step explanation:

Given:

Number of adults = 2

Number of Children = 6

Total Amount of tickets sold = $54.

We need to find the price of one children's ticket and one adult ticket.

Solution:

Let the Cost of 1 adult ticket be 'x'.

Now Given:

Children tickets are on sale,half price of adult tickets.

Cost of 1 Children ticket = $\frac{1}{2}x$

Total Amount is equal to Number of adults multiplied by Cost of adult ticket plus Number of Children multiplied by Cost of Children ticket.

Framing in equation for we get;

$2x+\frac{1}{2}x\times 6=54\\\\2x+3x=54\\\\5x=54\\\\x=\frac{54}{5} = \$10.8$

Cost of 1 adult ticket = $10.8

Cost of 1 children ticket = $\frac{x}{2}=\frac{10.8}{2} = \$5.4$

Hence Price of 1 adult ticket is <u>$10.8</u> and Price of 1 children ticket is <u>$5.4</u>.

Find the angle measure.<br><br> The measure of angle XYZ is

shutvik [7]

Answer:

Step-by-step explanation:

<u>1st step is to solve x from ΔWXY</u>

∠W + ∠X + ∠Y = 180

where ∠W = 5x + 2

∠X = 7x + 4

∠Y = 180 - (15x - 18)

= 198 - 15x

now plugin values into the equation:

5x + 2 + 7x + 4 + 198 - 15x = 180

combine similar terms:

5x + 7x - 15x = 180 - 2 - 4 - 198

simplify:

-3x = -24

x = -24 / -3

x = 8

<u>2nd step is to substitute x = 8 into ∠XYZ</u>

∠XYZ = 15x - 18

∠XYZ = 15(8) - 18

∠XYZ = 102

Let's say that mary's collection is symbolized by x

2/3 x = 4h

x = 3/2 . 4h

x = 6h

The storybooks they have in total would be : 6h + 4h = 10 h
