The value of X that will make this rational expression undefined would be if X = 0.
40/100 in the simplest form is 0.4.
Math:
Think about it this way.
4/10 is 0.4 because 4 into 10 goes into 10 4 times, since you need to make it a decimal.
25 quarters because if you set up a system of equations you get x+y=30 since there are x number of half dollars and y number of quarters plus each other is 30. Next equation is .5x+.25y=8.75 half dollar is 50cents while a quarter equals 25 cents and together they have to equal 8.75. Now you eliminate one variable then you add the remaining variable and the amounts together then you divide if you eliminated the x variable your answer is the one you get after you divide. If you eliminate the y variable then you have to plug it then you get your answer. hope this helped

Answer:
x=36/11
Step-by-step explanation:
4(2x-1)=-3x+32
8x-4=-3x+32
8x-(-3x)-4=32
8x+3x-4=32
11x-4=32
11x=32+4
11x=36
x=36/11
The length and breadth(width) of the pool are

Let

From the question, we can build the following relationships

subtracting to eliminate
(we do not even need it!)

we can also build another relationship from the question. Since the area of the strip equals the area of the pool:

We have two unknowns,
and
. Eliminate 

If we solve the quadratic equation for
, we get

and

The length and breadth(width) of the pool are
