The length of a rectangle is five centimeters more than twice its width. the perimeter is 100 centimeters. use guess and check to find out how long and how wide the rectangle is.

Guessing and checking isn't the best solution, so I will demonstrate it another way.

Let x be the width. We know that the length is then 2x+5.

So, 2(x+2x+5)=100

3x+5=50

3x=45

So, x=15.

Therefore, the rectangle is 15 centimeters wide.

Guessing and checking could also work. Once you plug in a value, if it is less than 100, than increase you number. The other way works as well.

$650 per month plus utilities

step-by-step explanation:

just based on the info you gave, it would seem more cost effective to rent at $650 per month plus utilities.   if utilities are, in fact, $150 per month, your monthly living costs would be $800 as opposed to the other option of $825.
