Step-by-step explanation:

19.

$\frac{x-1}{2} - \frac{x-3}{5} - \frac{x-7}{10} + \frac{x-2}{5}$
$\frac{5(x-1)-2(x-3)-(x-7)+2(x-2)}{10}$
$\frac{5x-5-2x+6-x+7+2x-4}{10}$
$\frac{4x+4}{10}$
$\frac{2x+2}{5}$

20.

$\frac{2x+3}{2x} + \frac{x+3}{4x} - \frac{18x+6}{8x^{2} }$
$\frac{4x(2x+3)+2x(x+3)-(18x+6)}{8x^{2} }$
$\frac{8x^{2} +12x+2x^{2} +6x-18x-6}{8x^{2} }$
$\frac{10x^{2}-6}{8x^{2} }$
$\frac{5x^{2}-3}{4x^{2} }$

The perimeter of a rectangle is 162 inches. what are the dimensions of the rectangle if the length is 7 times than 3 times the w

ankoles [38]

Answer:

3.68 inches × 77.28 inches

Step-by-step explanation:

Given that,

The perimeter of a rectangle is 162 inches.

Let the width is b.

ATQ,

Length = 7 times than 3 times the width

l = 7(3b) = 21b ...(1)

The perimeter of a rectangle is given by :

P = 2(l+b)

Put all the values,

162 = 2(21b+b)

81 = 22b

b = 3.68 inches

Put the value of b in equation (1)

l = 21b

= 21 (3.68)

= 77.28 inches

Hence, the dimensions of the rectangle are 3.68 inches × 77.28 inches
