143 - 20% = 143 x (1 - (20/100)) = 143 x 0.8 = 114.4
from the given information,we get, angle b = x angle a = 4x - 5 we know that supplementary angles have 180 degree as their sum , so, 4x - 5 + x = 180 5x - 5 = 180 5x = 185 x = 37 so,angle a = 4x - 5 = 4 *37 -5 = 143 angle b = 37 also angle a + angle b = 143 + 37 = 180
the answer is 37 and here's why... x% * 110 = 40.7 x/100 * 110 = 40.7 x/100 = 40.7/110 x/100 = 0.37 x = 0.37 * 100 x = 37 --check your work-- 37% * 110 = 40.7 37/100 * 110 = 40.7 (37*110)/100 = 40.7 4070/100 = 40.7 40.7 = 40.7
1 x 143, 11 x 13
% rate:= (39/143) x 100%= 0.2727 x 100%= 27.27%
