A binary operation* is defined on the set R of real number by:a*b= a+b-2ab, where a, b€R find the identity element of under the operation*
determine the inverse under *of a general element aR starting which has no inverse

6xy and -16xy000000000

Aand b are correctly balanced reactions. they have the same number of atoms in both sides of the reaction

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
