Pierce is making a rectangular frame for a photo collage that has a perimeter of 72.2 72.2 inches. The length of the frame is 20

Allushta [10]

Answer:

$P = 2x+2y$ (1)

And we know that the lenght is y = 20.3. If we solve for x from equation (1) we got:

$P-2y = 2x$

$\frac{P-2y}{2} =x$

And replacing we got:

$x = \frac{72.2 in -2*20.3 in}{2}= 15.8 in$

And the width for this case would be 15.8 in

Step-by-step explanation:

For this case we know that the photo is rectangular. Let's define:

x = the width, y= the length

And we know that the perimeter is given by:

$P = 2x+2y$ (1)

And we know that the lenght is y = 20.3. If we solve for x from equation (1) we got:

$P-2y = 2x$

$\frac{P-2y}{2} =x$

And replacing we got:

$x = \frac{72.2 in -2*20.3 in}{2}= 15.8 in$

And the width for this case would be 15.8 in

Help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Yanka [14]

Answer:

The answer is A. k = 4.25.

Step-by-step explanation:

To find proportionality, solve for 8.5 divided by 2 and 17 divided by 4.

Both of those answers are 4.25, so that would be the final answer.

Spent Withdrew, Down,Decrease all have negative values

musickatia [10]

True, all of them represent a negative number, for example:

You have $60 and you spent $10, the remaining money is:

$60-10=50$

Your savings are $1000 and you make a Withdrawal of $500:

$1000-500=500$

In other words for calculation purposes, they all have negative values

Keith_Richards [23]

3x - 18 = 42
3x = 42 + 18
3x = 60
x = 60/3
x = 20
