Explain how you could use a number line to show that -4+3 and 3+ -4 have the same value. which property of addition states that the sums are equivalent?

For -4+3, plot -4 on the number line and move up three steps.
For 3+-4, plot 3 on the number line and move back four steps.
You should end at -1 both times.
This demonstrates the commutative property of addition.

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%
