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
100 & 140. The two numbers are: the mean ± half the range. Half the range is 40/2 = 20. So the two numbers are: 120 - 20 = 100 120 + 20 = 140
40 - 20 percent = 820% of 40= 20% * 40= 20%/100% * 40= 8
800 $20 bills would make 800. Assuming you mean $800, it takes 40 $20 bills to total $800
Note that 20 exactly divides 40 because 40 / 20 = 2. Then, the GCD of 20 and 40 is 20.

"Of" means to multiply. For example, what is 40% of 20? 20*0.4 =8
27.33333333
With a mean score of 110 and a standard deviation of 18, what percentage of scores would be less than 155?
If you mean factors, they are 1, 2, 4, 5, 8, 10, 20, 40
100 & 140. The two numbers are: the mean ± half the range. Half the range is 40/2 = 20. So the two numbers are: 120 - 20 = 100 120 + 20 = 140
40 - 20 percent = 820% of 40= 20% * 40= 20%/100% * 40= 8
20% of 40 is not greater than 40% of 20. The two are equal. 20% of 40 = 0.20 * 40 = 8 40% of 20 = 0.40 * 20 = 8
40 of 20 = 40 x 20 = 800 40% of 20 = 0.4 x 20 = 8
When there is an even number of items in the data set the median is the mean average of the middle two. The middle two are the two items themselves, namely 20 and 40, so the median is (20 + 40)/2 = 30.
