Help me pleas: Find the value of a and b when x=10

a = 5x (squared) ÷ 2

b = 2x (squared) (x-5) ÷ 10x

​

My guesses would be:

a 1250
b. 20

No solution : there is no number of boxes that she bought

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%
