"what plus what gives 21" or simply we can say: x + y = 21.
Choose any value of x(say, 2) then we get y = 21-2 =19.
If we put x = 20 then we get y = 1.
We can write a few pairs satisfying the condition as: (1,20), (9,12), (-21,42), (0,21), (2,19),...
There exists infinitely many values of x and y.
However, if we talk about only natural numbers then we can write all the values of x and y. But, if we talk about real numbers then we have infinite values of x and y.
6 + 3 + 21 + 63 + 21 = 114
55 + 34 + 31 + 27 + 21 + 21 + 20 + 17 + 15 + 15 = 256
The answer to 21 plus 16 is 37.
32+14+20+18+16+31+21+16=168
The statement 10 plus 21 equals 31 in total. It can also be written as 10 + 21 = 31.
You can't. 17 + 2n = 21 + 2n gives: 2n = 4 + 2n which gives 0=4 which is not possible so the sum is not solveable.
6 + 3 + 21 + 63 + 21 = 114
Adding 79 to 321 gives 400 as the result(79+321).
To find the value of d. SO: if d + 21 = 25, subtract 21 from each side, gives d = 25 - 21, so d = 4
21
21+21+19+19=80
21+21+17=59
(21-21)+(21-21)+21 = 0+0+21 = 21
what plus what gives me 24
55 + 34 + 31 + 27 + 21 + 21 + 20 + 17 + 15 + 15 = 256
The answer to 21 plus 16 is 37.
The answer depends on the tax rate and since you have not shared that crucial bit of information, it cannot be answered. However, if you find the tax, say it is 21%. You divide by 100, multiply by (100+21) and this gives total plus tax.
