9 x 20 = 180
Subtract 9 from each side. ( subtraction; both sides ) X + 9 = 20 X + 9 - 9 = 20 - 9 X = 11 -----------------check in original equation 11 + 9 = 20 20 = 20 checks
9 out of 20 = 9/20 = 9 ÷ 20 = 0.45: 0.45 x 100 = 45%
For 9 ft x 20 ft = 180 ft²
% rate= (9/20) x 100% = 45%
20/x = 9 Divide each side by 20. you get 1/x = 9/20. flip both sides. you get x = 20/9
9 x 20 = 180
Subtract 9 from each side. ( subtraction; both sides ) X + 9 = 20 X + 9 - 9 = 20 - 9 X = 11 -----------------check in original equation 11 + 9 = 20 20 = 20 checks
25 x 9 = (20 x 9) + (5 x 9)20 x 9 = 1805 x 9 = 45180 + 45 = 22525 x 9 = 225
The Answer For 9 X 9 X 9 Is 729
The value of X in the equation X - 9 = 11 is 20. This obtained by adding both sides of the equation with 9.
9 x 28 = (9 x 20) + (9 x 8) 9 x 20 = 180 9 x 8 = 72 180 + 72 = 252 9 x 28 = 252
(20/5)/(20/9) is the same as (20/5)X(9/20) This can be reduced to (1/5)X(9/1) 9/5.
20 x 9 = 180
9 out of 20 = 9/20 = 9 ÷ 20 = 0.45: 0.45 x 100 = 45%
For 9 ft x 20 ft = 180 ft²
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.
