20
I guess you mean: What number when you subtract 20, gives 40 as the answer?x - 20 = 40.Add 20 to both sides: x - 20 + 20 = 40 + 20x = 60
Oh, dude, 60 is like 40 higher than 20. Like, you just take 60 and subtract 20, and boom, you get 40. Basic math, my friend.

To translate the point (10, -60) 40 units down, you subtract 40 from the y-coordinate, resulting in -100. To translate it 30 units left, you subtract 30 from the x-coordinate, resulting in -20. Therefore, the new coordinates after the translation are (-20, -100).
To decrease a number by a percentage, first calculate the amount of the decrease by multiplying the original number by the percentage (expressed as a decimal). Then, subtract this amount from the original number. For example, to decrease 200 by 20%, calculate 20% of 200 (which is 40) and then subtract 40 from 200, resulting in 160.
82 subtract by 20 = 62

say you have 7/5 and 8/4. to subtract them, all you have to do is give them a common denominator (the number on the bottem) the lowest commen denominator (LCM) is 20 to get both of them with a denominator of 20 multiply by 4/4 and 5/5 respectivly. 7/5 x 4/4 = 28/20 8/4 x 5/5 = 40/20 then subtract. 40/20 - 28/20 = 12/20
Subtract a negative 1. 19 - (-1) = 20
7 times 6 is 42. If you subtract two, you get 42-2= 40.
