Simon says "five times my age 4 years ago is the same as 3 times my age in 2 years". how old is simon now

Simon is 13. Simon's age can be represented algebraically as x, thus the following equation can be drawn; 5(x-4) = 3(x+2). Expanding the equation 5x-20 = 3x + 6, and moving the x's to one side, and the integers to the other you get 2x = 26, and x=13. To check results (13-4)*5=45, and (13+2)*3=45.

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%
