-32 = 4c -12
add -34 by 12 which is -20
divide it by 4
c = -5
x/.75=x-56/0.4
0.4x=.75x-42
-0.35x=-42
x=120
I set up a proportion in which x=the tank when it is 3/4 full. When the tank is 3/4 full, solving the proportion tells us the x=120 litres. 120/3=40, and 120+40 is 160, showing that a tank completely full would indeed hold 160 litres.
Hope this helps!
C=1/6 of x
D=55/1/2
1/6 of 111/2=110.167
55.08
=55 inches
The mean would be 92. Because you add them all up then divide by how many there are
