Let x be the measure of leslie wing insect wing=1m=100cm insect wing= 1/10 of leslie wing 100cm=1/10 *x 1000cm=x x=1000cm x=10m therefore the leslie wing = 10m
X + y = 12 / x (-45); Then, -45x - 45y = -540; We have 80x + 45y = 645 and -45x - 45y = -540 ________________ 35x = 105; Finally, x = 105÷35; x = 3; y = 12 - 3; y = 9;
