The length of a rectangle is 5 centimeters less than twice its width. The perimeter of the rectangle is 26 cm. What are the dime

iris [78.8K]

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

We know that:

$\begin{cases}l = 2w-5\\2(l+w)=26\end{cases}$

Substitute the first equation in the second:

$2(l+w)=26 \iff l+w=13 \iff 2w-5+w=13 \iff 3w = 18 \iff w=6$

Use the first equation to compute the length:

$l=2\times 6 - 5 = 12-5=7$

So, length = 7 cm; width = 6 cm

Gloria received a 4 percent raise and is now making $24,960 a year, what was her salary before the raise?

Svetradugi [14.3K]

She gets a 4% raise so her new pay is 100% + 4% of her previous pay.

104% = 1.04 as a decimal.

Divide her new pay by 1.04:

24,960 / 1.04 = 24,000

Her previous pay was $24,000
