The answer is 35.4. 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.
30 + 10 + 5 + 5 = 50
30
30 + 5 = 35
5 + 5 + 5 + 5 + 5 + 5 = 30
8+1+5+5+3+8+10+30=70 The answer is 70
30 + 5 + 210 = 245
3(6a + 5) + 30 18a + 15 + 30 18a + 45
15093570000 + 80000 + 900 + 30 + 5 = 150935

3 + 6 + m + 12 + 5 = 30 9 + m + 17 = 30 m + 26 = 30 m = 30 - 26 = 4
3/5 plus 1/6 = 23/30
