Answer:

Width = 46 yards, Length=175 yards.

Step-by-step explanation:

Perimeter of rectangle = 2(length) +2(width)

We know that the length is 4width-9, so we can substitute that in for the length.

442= 2(4w-9)+2w, Next distribute

442=8w-18+2w, Now add like terms

442=10w-18, Move 18 to the other side

460=10w, solve for w

width= 46 yards.

Now we have 442=2(length)+2(46), subtract 92 to the left

350=2(length), divide by 2

Length= 175 yards.

Check your work with P=2(175)+w(46)

P=442 yards.

What is the percent of change from 4,000 to 600?<br> work too plz

xenn [34]

$\frac { n }{ 100 } \cdot 4,000=600\\ \\ 4,000\cdot n=60,000\\ \\ Therefore:\\ \\ n=\frac { 60,000 }{ 4,000 }$

$\\ \\ =\frac { 60\cdot 1,000 }{ 4\cdot 1,000 } \\ \\ =\frac { 60 }{ 4 } \\ \\ =15$

As 15% of 4,000 is 600, the percentage change was -85%.
