Step-by-step explanation:
24.1x 30y The line is kinda in 24.1
82.5 / 5.5 = 15
15 hrs.
i think that should be the answer but i didn't use the 2.3 -meter-thick clue...
Since the x value can be changed to anything other than 4 (because then you would be dividing by 0 in x-4), the answer is: All real numbers except 4.
0.6 matches with six-tenths because if you divide 6 and 10 together you will get 0.6
Hope this helped! :)
