Answer:

x = 10

y= 12

Step-by-step explanation:

We know that TSV = 90 degrees

5x+4x = 90

9x = 90

Divide by 9

9x/9 = 90/9

x = 10

We know that RSU = 180

10y+10 +5x= 180

10y + 10 + 5(10) = 180

10y + 10 +50 = 180

10y +60 = 180

Subtract 60 from each side

10y = 120

Divide by 10

y = 12

Answer:

(1-2) LS = 288cm² TS = 378cm²

(3-4) LS = 1419.2 TS = 1673.5

(5) LS = 543 TS = 606

Step-by-step explanation:

(1-2)

7 1/2 = 7.5

7.5 x 15 = 112.5

9 x 12 ➗ 2 = 54

54 x 2 = 108

9 x 7.5 = 67 .5

(3-4)

3.14 x 81 = 254.3

(5)

9 x 15 = 135 x 2 = 270

15 x 7 = 105 x 2 = 210

9 x 7 = 63

Answer:

Price of a senior citizen ticket is $4 and price of a student ticket is $15 .

Step-by-step explanation:

Let us assume that the price a senior citizen ticket be x .

Let us assume that the price a student citizen ticket be y .

As given

The school that Jack goes to is selling tickets to a choral performance.

On the first day of ticket sales the school sold 9 senior citizen tickets and 8 student tickets for a total of $156.

Equtaions becomes

9x + 8y = 156

As given

The school took in $163 on the second day by selling 7 senior citizen tickets and 9 student tickets.

Equations becomes

7x + 9y = 163

Multipy 9x + 8y = 156 by 9 .

81x + 72y = 1404

Multiply 7x + 9y = 163 by 8 .

56x + 72y = 1304

Subtracted 56x + 72y = 1304 from 81x + 72y = 1404 .

81x - 56x + 72y - 72y = 1404 - 1304

25x = 100

$x = \frac{100}{25}$

x = $ 4

Putting value of x in the 56x + 72y = 1304 .

56 × 4 + 72y = 1304

224 + 72y = 1304

72y = 1304 - 224

72y = 1080

$y = \frac{1080}{72}$

y = $15

Therefore the price of a senior citizen ticket is $4 and price of a student ticket is $15 .
