HELP PLEASE I REALLY AM CONFUSED PLEASE THANK YOU

Answer 1

Answer:

x=5/4

r =20

Step-by-step explanation:

On the left we have 9x -7

On the right side we have -3x + 8

9x-7 = -3x+8

Add 3x to each side

9x+3x-7 = -3x+3x+8

12x -7 = 8

Add 7 to each side

12x -7+7 = 8+7

12x = 15

Divide each side by 12

12x/12 =15/12

x = 5/4

Carnival T

7+.5r

Carnival Q

12+.25r

Set them equal for the cost to be the same

7+.5r=12+.25r

Subtract .25r from each side

7+.5r-.25r=12+.25r-.25r

7+.25r = 12

Subtract 7 from each side

7-7+.25r = 12-7

.25r = 5

Divide each side by .25

.25r/.25 = 5/.25

r=20
