Using DeMoivre's theorem, and the fact that any root in the first quadrant has argument between and , we get
so the missing value is 45.
1.2(w+5)=3
1.2w+6=3
-6 -6
----
1.2w = -3/1.2
w= -2.5
Since it's 0.6 kg for 5 gallons, we'd want to find the unit rate aka the amount of kg's per gallon. To find that, we have to see how many times 5 goes into 0.6, which is 0.6/5=0.12 for 1 gallon. Multiply that by 7 to get 0.84 for 7 gallons!
Well, 180 - 126 = 54
54 + 58 + x = 180
112 + x = 180
-112 -112
x = 68
