20 + 27 = 47
27 + 20 = 47
13 + 16 + 18 + 20 + 21 + 26 + 27 + 27 + 28 + 36 + 39 + 42 + 43 = 356
55 + 34 + 31 + 27 + 21 + 21 + 20 + 17 + 15 + 15 = 256
If you add 27 and 8, the answer is 35. 7 plus 8 is 15 and add it to 20, the answer is 35.
3y - 7 + y + 27 = 6y + 20 - 4y Collect terms: 4y + 20 = 2y + 20 Subtract 20 4y = 2y The only way that can happen is if y = 0
27
27/20 or 2 and 7/20
-20
-x + 7 = 27 Subtract 7 from both sides: -x = 20 or x = -20
The sum of 20 added to itself 20 times is calculated by multiplying 20 by 20, resulting in 400. Therefore, the answer to the given equation is 400.
3/5 + 3/4 = 12/20 + 15/20 = 27/20 = 1 7/20
Add 7x to each side: 136 = 27x + 20 Subtract 20 from each side: 116 = 27x Divide each side by 27: x = 116/27 = 4 & 8/27.
