The answer is 150. 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.
100 + 100 + 50 = 250
-100
x + 50 = 2x + 100 50 = 2x+100-x 50 = x + 100 50-100=x -50=x -50+50=0 -100+100=0 it is zero
100 + 50 + 100000000 = 100000150
1 100 + 50 + 90 + 45 _____ 285
100 plus 50=150. 150+20=170.
50 + 50 = 100
The sum of 70 + 30 + 1250 + 50 + 100 = 1500
2,500 Or; 50+50=100
50% + 50% = 100%
-50 - 200 + 100 + 200 - 150 = -100. Your answer is -100. I hope I've helped you.
100 + 0.08N = 50 + 0.16N100 - 50 = 0.16N - 0.08N50 = 0.08NN = 50/0.08N = 625
