The school that Jaidee goes to is selling tickets to the annual talent show. On the first day of ticket sales the school sold 10

Olenka [21]

The price of a senior citizen ticket is $8 and the price of a student ticket is$ 10

Step-by-step explanation:

Let the cost of one seniors citizen ticket be x and student be y

First day:

10 seniors citizen tickets and 11 student for a total of $190.

10x + 11y = 190-----------------------------(1)

Second day:

$160 on the second day by selling 5 senior citizen tickets and 12 student tickets.

5x + 12y = 160---------------------------------(2)

Multiply eq(2) by 2

10x + 24y = 320----------------------------(3)

Subtract eq(1) from (3)

10x + 24y = 320

10x + 11y = 190

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

0x + 13 y = 130

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

13y = 130

$y = \frac{130}{13}$

y = 10-------------------------------(4)

Substituting (4) in (2)

5x + 12(10) = 160

5x + 120 = 160

5x = 160-120

5x = 40

$x = \frac{40}{5}$

x = 8

Determine the lateral area and surface area of the given prism. Round answers to the nearest whole number.

vazorg [7]

Answer:

Lateral Area = Area of 2 triangle + Area of slant rectangle + area of back rectangle

Lateral Area = (5m)(3m) + (6m) (36m) + (3m) (36m)

LA = 15m² + 216m² + 108m²

LA = 339 m²

SA = (5m)(3m) + (6m) (36m) + (3m) (36m) + (5m)(36m)

SA = 15m² + 216m² + 108m² + 180 m²

SA = 519 m²

G) X-3 (x - 2) = 3 (2-x)

Paraphin [41]

x - 3( x - 2 ) = 3 ( 2 - x )

Multiply 3 with x - 2 on LHS and 3 with 2 - x on RHS

or, x - 3x + 6 = 6 - 3x

Now take -3x to LHS and change its symbol to +. And take 6 to RHS and change it to negative.

or, x - 3x + 3x = 6 - 6

-3x and 3x will cancel out and also 6 and -6 will also get cancelled out.

or, x = 0

Answer:

x = 0
