Answer:
k=3
Step-by-step explanation:
The given system of equations are
We need to find the value of k if the given system of equation have infinite number of solutions.
If two equations 
and 
have infinite number of solutions, then
Using this we get
Therefore, the value of k is 3.
Answer:
Within 52 weeks, the amount of water in the two fish tanks will be the same.
Step-by-step explanation:
First, let's make the two equations equal to each other by placing an equal sign.
832 - 5x = 1040 - 9x
Now, that they are equal to each other, we can solve for x.
Okay, so we can move -5x to the other side by adding both sides with 5x.
832 = 1040 - 4x
Then, subtract 1040 from both sides to move it to the other side.
832 - 1040 = -208
-208 = -4x
Lastly, divide both sides by -4 to get the value of x.
-208/-4 = 52
x = 52
