A rectangular pool is to be built on a lot that measures 20 m by 12 m. A wooden deck of uniform width, equal to the area of the

frutty [35]

The length and breadth(width) of the pool are

$l\approx15.7m\text{ and }b\approx7.7m$

Let

$l=\text{length of the side of the pool}\\b=\text{breadth of the pool side}\\w=\text{the width of the strip of deck surrounding the pool}$

From the question, we can build the following relationships

$l+2w=20\\b+2w=12$

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

$l-b=8\\b=l-8$

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

$lb+lb=2lb=20\times 12\\lb=120$

We have two unknowns, $l$ and $b$ . Eliminate $b$

$lb=120\\l(l-8)=120\\l^2-8l-120=0$

If we solve the quadratic equation for $l$ , we get

$l=4+2\sqrt{34}\approx 15.7m$

and

$b=l-8\\b=(4+2\sqrt{34})-8\\b=2\sqrt{34}-4\approx7.7m$

The length and breadth(width) of the pool are

$l\approx15.7m\text{ and }b\approx7.7m$

Tanisha is thinking of two numbers. The sum of the numbers is 5. If the lesser number is subtracted from the greater number the

AysviL [449]

For this case we have the following system of equations:

$x + y = 5\\x - y = 7$

From the first equation we have:

$x = 5-y$

We substitute in the second equation:

$5-y-y = 7\\5-2y = 7$

We subtract 5 from both sides of the equation:

$-2y = 7-5\\-2y = 2$

We divide -2 on both sides of the equation:

$y = \frac {2} {- 2}\\y = -1$

So:

$x = 5-y\\x = 5 - (- 1)\\x = 5 + 1\\x = 6$

So, the system solution is: $(x, y) :( 6, -1)$

Answer:

See attached image $(x, y) :( 6, -1)$
