20 + x
If x stays the same the expression stays the same. Since the expression involves negative x, the value of the expression decreases as x increases.
20 cubed = 20 x 20 x 20 = 8000
20/x = 9 Divide each side by 20. you get 1/x = 9/20. flip both sides. you get x = 20/9
(20 + x)-3
A 20 x 20 room will have a perimeter of 20 + 20 + 20 + 20 = 80.
The amount of increase is 20. The percent increase is 20/100 X 100 = 20%
20% increase = 2860 = 10% increase x 2 = 1430 x 2 = 2860
The increase would be 11, from 55 to 66. 20% of 55 = 0.20 x 55 = 11
30/25 x 100 - 100 = 20 Therefore, the percentage increase is 20 percent.
54 - 45 = 9 / 45 = 0.2 x 100 = 20% increase
Percentage increase from 50 to 70 is (20/50) x 100 = 40% Percentage decrease from 70 to 50 is (20/70) x 100 = 28.5714%
It is an increase of 20%. 50 is the increase, divided by the starting figure, then x 100 to give in percentage.
3295.44 x 1.2 = 3954.528 Therefore, increasing 3295.44 by 20 percent gives 3954.528.
20%= 20/100 = 0.2100%= 100/100= 1100%= 40100% + 20% (increase)= 120%= 1 + 0.2= 1.240 increased by 20%= 40 x 1.2= 48
20 40 60 80 101 x 20 = 202 x 20 = 403 x 20 = 604 x 20 = 805 x 20 = 1006 x 20 = 1207 x 20 = 1408 x 20 = 1609 x 20 = 18010 x 20 = 20011 x 20 = 22012 x 20 = 24013 x 20 = 26014 x 20 = 28015 x 20 = 30016 x 20 = 32017 x 20 = 34018 x 20 = 36019 x 20 = 38020 x 20 = 400
20 cubed cubed = [203]3 = (20 x 20 x 20)3 This equals 20 x 20 x 20 x 20 x 20 x 20 x 20 x 20 x 20 which = (20)9 The rule to work it out is:multiply the two exponents ie 3 x 3 = 9 206 is 20 x 20 x 20 x 20 x 20 x 20 which is obviously less than 209.
