The width of a rectangle is 9 inches shorter than the length. if the perimeter is 26 inches. find the width and length.

Length: 11

Width: 2

Step-by-step explanation:

If length is x then width is x-9

That means:

    26 = x+x+x-9+x-9 = 4x-18  which means:

    44=4x    x=11

Length=x = 11

Width = x-9 = 11-9 = 2

expression #3 is not equivalent. the others are.

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
