Xion and kyndol wanted to have a contest to see which of their paper airplanes could fly the longest distance. xion's plane flew four meters. kyndol's plane flew 79 centimeters. how much further did xion's plane fly in meters?

3.21 meters

There's 100 centimeters in a meter (centi means 100) so 79 centimeters equals 0.79 meters. So 4 - 0.79 is 3.21

Sample response: No, Yin is not correct. If x = 19, the measure of angle ABC = 4(19) - 12 = 64. Therefore, the two base angles measure 64. An equilateral triangle is equiangular, so each angle would have to measure 60° because there are 180°in a triangle.
