Lol I'll just comment to get 5 points
If you are working with time or days, you can't put in a negative value because if you are doing an experiment, you can't go back in time to do that experiment to gather data. (Time for the most part considered to be an input value so that's why I used it as an example.)
1.) 58
2.) 205
3.) 134
4.) 150
5.) 21
6.) 670
7.) 33
8.) 50/7 or 7 1/7
9.) 42
These are all your answers
Multiply the top one by 3 for x, so you can eliminate x and find y
then plug in the y into one of the equations to find x
44 fl oz there are 2000 pounds in a tone for x amount of supplement… ( supplement volume)/(weight in pounds) = x/(5.5*2000)=1/250 multiplied by 11000
x=11000/250=44 fl
