n + 1/4 = 9/20 n + 5/20 = 9/20 n = 4/20 = 1/5
The answer is 8. One fifth of 20 is 4 because 20/5 is 4, and 4*2=8
2x + x + 4 +2x = x + 20 5x + 4 = x + 20 5x - x = 20 - 4 4x = 16 x = 4
Why is 5 x -4 = -20 ? Think of it as money. If I have four dollars then that's +4. If I owe 4 that's -4. If 5 of us owe 4 that means 20 is owed = -20 dollars a PLUS times a MINUS is a MINUS. Accept it.
well its impossible to answer since there is no x=? if it was 5x+20=40 then x=4 5 x 4=20+20=40
4/4+4*4=20 1+4*4=20 5*4=20 20=20
4 is 20 percent of 20. 20 percent is equal to .20, so .20 x 20 = 4
percent of 4/20 = 20%4/20 * 100% = 20%
If 20% = 4 We know that 20% x 5 = 100% So 4 x 5 = 20 So 4 is 20% of 20.
4 divided by 20 is 0.2, which equals 20%. So 4 is 20% of 20.
It is: 4/20 = 20%
20 - 4 or 4 - 20 , whichever is not negative. In this case it is 20 - 4 = +16
The percentage of 4 out of 20 is 20%.
20 = 4 × (4 ÷ 4 + 4)
4 out of 20:= 4/20 or 1/5
Yes, because 4 times 5 equals 20. So 4 is a factor of 20.
The greatest common factor of -4 and -20 is -4.-4 x 1 = -4-4 x 5 = -20
