Answer:
C. 2x
Step-by-step explanation:
Let
B's age = x years
A's age = 2 times older than B
= 2 * x
= 2x years
A's age = 2x years
For instance, if B's age is 17 years
Then,
A's age = 2x
= 2(17)
= 34 years old
-1/3x-4/3y=2
1/3x-2/3y=4
First realize that the coefficient of x is -1/3 and 1/3 which can be eliminated with addition
Adding the two equations together gets
-6/3y=6
Simplify
-2y=6
y=-3
Substitute back into original equation
1/3x-2/3(-3)=4
1/3x+2=4
1/3x=2
x=6
Answer
x=6, y=-3
Check answer
-1/3(6)-4/3(-3) =?= 2
-2+4=2
2=2
Done!

Q: can you find the volume of the tank based on the opposite sides as the bases.
This one was a tricky one lol.
To find volume you need a formula:
Formula for volume varies on the shape of the object.
<span><span>Cube = a 3<span>a is the side length
</span></span><span>Rectangular prism = a * b * c<span>a, b, c are the length, width, and height
</span></span><span>Cylinder = π * r 2 * h<span><span>r is the radius of the circular base</span><span>h is the height
for this one you would need the Rectangular prism formula.
A: No you cannot find the volume because you need length, width, and height to figure out the volume of the rectangular prism.
Hope this helped! :)
