Priya, Han, and Mai each measured one of the circular objects from earlier. - Priya says that the bike wheel is 24 inches. - Han says that the yo-yo trick is 24 inches. - Mai says that the glow necklace is 24 inches. Do you think that all these circles are the same size?

step-by-step explanation:

if x = 1, then the answer is 3.5

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.
