100/50 = 2 2 x 2 = 4 4 - 2 = 2
The following answer is based on the correct order of operations. If you meant something different, please alter the question accordingly. 5x+3x+2-3x+2x+1 7x+3
20 + 20 + 20 + 20 + 20 + 20 + 20 + 20 + 20 + 20 + 20 + 20 + 20 + 20 + 20 + 20 + 20 + 20 + 20 + 20 = 400.
20 of 20 = 20 x 20 = 400 20% of 20 = 0.2 x 20 = 4
"20 more than 20" means that you are adding 20 by 20. Then: 20 + 20 = 40 So 40 is 20 more than 20 because 40 - 20 = 20!
There are 20 questions.
The LCM of 20 and 20 is 20.
20 + + 20 + 20 = 60
A 20 x 20 room will have a perimeter of 20 + 20 + 20 + 20 = 80.
if you want the whole number, multiply 20 by 7. 20+20+20+20+20+20+20=140
There is only one number that equals 20, and that is 20.
