Icurrently have a c- in math and i need an a before summer

estimate 3.6 +8.2 by rounding to the nearest whole number

3.6 can be rounded to 4 and 8.2 can be rounded to 8. Now, all we have to do is 4 + 8, and the answer is 12. 

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%
