Answer:

  p = 20

Step-by-step explanation:

Collecting terms gives ...

  (4/5 -3/5)p - 4 = 0

  1/5p - 4 = 0

Multiplying by 5, we get ...

  p - 20 = 0

Then, adding 20 gives the solution:

  p = 20

the length of a rectagle is 5 in longer than its width. if the perimeter of the rectangle is 56 in, find its length and width
lisabon 2012 [21]

Answer:

Step-by-step explanation:

Let the width of the rectangle = x

As length is 5 inches longer than width, we have to add 5 to width

Length = x + 5

Perimeter of ractangle = 56 in

2* (length + width) = 56

2*( x + 5 + x) = 56

2* (2x + 5)    = 56

Use distributive property: a*(b +c) =(a*b) + (a * c)

2*2x + 2*5   = 56

4x  + 10 = 56

Subtract 10 from both sides

4x = 56- 10

4x = 46

Divide both sides by 4

x = 46/4

x = 11.5

Width = 11.5 in

length = 11.5 + 5

            = 16.5 in

marshall27 [118]
Your ratio is 6:5

This means that it is 6/5.

You have to find a common number to either divide or multiply that can work for both the numerator and denominator.

6/5 doesn't have any common number to divide without getting a remainder

But we can multiply by a common number such as 2

6×2 = 12
5×2 = 10

= 12/10. ☆= the ratio is 12 : 10

or even by 3, =the ratio 18:15
