Solution:
3,500,000 - 2,030,000 = 1,470,000 square miles

3,500,000-2,030,000= 1,470,000 square miles. Hope this helps!

Gala2k [10]

Answer: 210 advanced tickets were sold. 130 same day tickets were sold.

Step-by-step explanation:

x= advanced tickets y=same day tickets

2x+3y=810 this equation represents the money

x+y=340 this equation represents the total number of tickets

x+y=340

-x -x

y=-340-x 2x+3(340-x)=810 210+y=340

2x+1020-3x=810 -210 -210

-x+1020=810 y=130

-1020 -1020

-x=-210

-1 -1

x=210
