Answer the question in the included image.

1/3

Step-by-step explanation:

x(x-2)+2x+36-3x+46=100;  x>0

x²-2x+2x-3x+82-100=0

x²-3x-18=0

x²-6x+3x-18=0

x(x-6)+3(x-6)=0

(x+3)(x-6)=0  => x=6

=> 6(6-2)+2*6=36 stamps in the 20th century

2x=2*6=12 stamps in the 20th century and British stamps

Probability=12/36=1/3

she was supposed to add the hours(38.5) and multiply the amount of money she earned(7.50) resulting in $288.75 .

correct me if i'm wrong and if it is i'm truly sorry.
