Answer:
A)2y=x+2
Step-by-step explanation:
If you would like to solve the system of equations, you can do this using the following steps:
3x + y = 3
x + y = 2 ... y = 2 - x
_________________
<span>3x + y = 3
</span>3x + 2 - x = 3
2x = 3 - 2
2x = 1
x = 1/2
y<span> = 2 - x = 2 - 1/2 = 1 1/2 = 3/2
(x, y) = (1/2, 1 1/2) = (1/2, 3/2)
The correct result would be </span><span>C) x = 1/2, y = 3/2.</span>
Answer:
112 m³
Step-by-step explanation:
Let's calculate first the voulume of the tank
the volume of thi tank is given by :
- V = l*w*h
- l is the length
- w is the width
- h is the height
so the volume is :
Multiply by 2/3 to get the volume of the water
- V' = 168*(2/3)
- V' = 112 m³
