The answer is 259. Simply add the numbers together arithmetically as you would for the problem two plus two. To check your work, a calculator is the best option.
800 + 800 + 800 + 800 + 800 = 4,000
4849 + 251 = 5100
814 = 563 + 251
251
If -8x+3=251, then 8x=-248. Therefore, x=-31.
x=156
500 plus 800 equals 1,300.
50 plus what = 850
Yes, 800 plus 800 equals 1600. When you add these two numbers together, the sum is indeed 1600.
600 + 500 + 800 + 900 + 9234 = 12034
200000 + 60000 + 2000 + 800 + 1 = 262801
100 + 700 = 800
