The equation "14 plus blank equals 30" can be solved by subtracting 14 from both sides to isolate the blank variable. This gives us blank = 30 - 14, which simplifies to blank = 16. Therefore, the missing number that, when added to 14, equals 30 is 16.
Here are all the numbers that when added equal 30: 1+29= 30 2+28=30 3+27=30 4+26=30 5+25=30 6+24=30 7+23=30 8+22=30 9+21=30 10+20=30 11+19=30 12+18=30 13+17=30 14+16=30 15+15=30 16+14=30 17+13=30 18+12=30 19+11=30
It is: -16+(-14) = -30
286
60 + 60 + 60 + 50 + 50 + 40 + 30 = 350
10
30
It is: 30
-30 plus 60 = 30
I am having difficulty understanding your question. 12 + 20 = 10 is obviously false (12 + 20 = 32).If 4x + 14 = 2x + 30, then x must equal 8.
30 + 80 = 110
In the equation 14 + 16 = 30, 14 and 16 are addends. Addends are the numbers being added together in an addition problem. In this case, 14 and 16 are the addends that, when combined, equal 30.
half of 30 is 15, so 15 added to 15 would equal 30. if you go from there and add one number and subtract one number from each 15 (14 plus 16, 13 plus 17, ect...all the way to 0 plus 30) these numbers will also total to 30.
-30
30 + 50 + 70 = 150
2+40+30=72
-30
