$10 = \frac{30}{3 } \\ 1 + \frac{2}{3} = \frac{5}{3} \\ \frac{30}{3} \div \frac{5}{3} = \frac{30}{3} \times \frac{3}{5} = 8glasses$

The width of a rectangle is 5 units less than the length. The area of the rectangle is 6 units. What is the width, in units, of

Readme [11.4K]

Answer:

The width of rectangle is 1 unit.

Step-by-step explanation:

Given:

The area of rectangle is 6 units and its width is 5 units less than the length.

So, to find the width of rectangle.

Let the length be $x$ and the width be $x-5$ .

Now, to find the width we put the formula of area of rectangle:

Area = length × width

$6= x\times (x-5)$

$6=x^{2}-5x$

$0=x^{2}-5x-6$

$0=x^{2}-6x+x-6$

$0=x(x-6)+1(x-6)$

$0=(x-6)(x+1)$

<em>On solving equation we get:</em>

$x-6=0, x+1=0$

Therefore, we take the value x=6 as it is positive value:

$x-6=0$

$x=6$

So, the width of rectangle:

Width = $x-5$

= $6-5$

= $1$

Therefore, the width of rectangle is 1 unit.

Consider the following pair of equations:

Oksana_A [137]

There is a special kind of substitution which some books call it by comparison.

When the two equations are both
y=some function of x
y=some other function of x, then
we can substitute the second equation into the first giving
some function of x = some other function of x and start solving.

For example,
<span>y = –2x + 8
y = x – 1
substitute second into first
x-1=-2x+8
isolate x on left,
3x=9
x=3
second step is to substitute x=3 into second equation to get
y=x-1=3-1=2
Therefore the solution is (3,2)</span>
