For an experiment to be conducted in a laboratory, the temperature t must be colder than 45 degrees Fahrenheit. complete the following inequality by dragging the correct symbol to the box. (,≤,≥ t ___ 45) show work if possible

i think its a and d

step-by-step explanation:

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.

there is no answer sorry!
