Answer:

The following expression can be used to represent the perimeter of rectangle ABCD: 16x-12

Step-by-step explanation:

Let l be the length of rectangle and w be the width of rectangle.

Given that:

l = 5x+1\\w = 3x-7

The perimeter of a rectangle is given by the expression:

P = 2(l+w)

Putting the values of length and width, we get

P = 2\{(5x+1)+(3x-7)\}\\P = 2\{5x+1+3x-7\}\\P = 2(8x-6)\\P = 16x-12

Hence,

The following expression can be used to represent the perimeter of rectangle ABCD: 16x-12

Recycling one glass bottle can save enough energy to power an oven for 7.5 minutes. A glass bottle weighs 500 grams. Glass used
musickatia [10]

This is a units conversion problem: you have time and you want to convert that to money. Any units conversion problem involves multiplication by 1 in various forms. When you are given 7.5 min = 1 bottle = 500g, you know that (500 g)/(7.5 min) = 1 because the numerator and denominator are equal. (Of course, you are aware that 500 g = 0.500 kg.) The idea is to choose the forms of 1 that cause units you don't want to cancel, leaving only the units you do want.


6\,h\times \dfrac{0.500\,kg}{7.5\,min}\times \dfrac{60\,min}{1\,h}\times \dfrac{5\,p}{1\,kg}\\\\=\dfrac{6\cdot 0.500\cdot 60\cdot 5\,p}{7.5\cdot 1\cdot 1}=120\,p


The glass for recycling that would save enough energy to power an oven for 6 hours costs 120p.
