i don't even know man. edge inuity be messing with us. i had to ask a question too.

t

step-by-step explanation:

ever thing time 1 is a multiply by 1 it get  

y=sec x is the correct answer

~batmans wife dun dun

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.
