3x-3y = x +5
-3y= -2x+5
y= 2/3x -5/3
Answer:
no change
Step-by-step explanation:
The system would be at equilibrium meaning there would be no change
5/7, I don't know what that is as a decimal, but I hope it helps
We have two questions, but we need to find the volume of the spherical tank first.
So the formula we will use to find the volume is:
(4/3)πr³=V
Let's fill in the information we have and solve. We will be using 3.14 for pi.
(4/3)(3.14)6³
(4/3)(3.14)(216)
4.1867×216
I'll be using the repeating decimal for 4.1867, I rounded to 7, but there is a repeating 6.
904.32
So the volume is 904.32 yards³ (or 904.78 if using the full pi)
We have to multiply the volume by 7.15.
904.32×7.15
6,465.89
It will cost $6,465.89 to fill the tank with the liquid.
Answer:
divide each side by -5
Step-by-step explanation:
-5m = -40
divide each side by -5
-5m/-5 = -40/-5
m = 5
