Explain how you could use a property of equality to show the following: if 3x=28 then 3x-5=23

To get the equations to equal each other, all you have to do is add five to each side on the equation 3x - 5 = 23.

If you add five, both equations will then be 3x = 28.

I hope that helps!

Answer is a not really sure tho

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%
