Answer:

98 = 2w + 2L,

L = 3w

Step-by-step explanation:

Use the perimeter formula:

2) Perimeter = 2w + 2L (where w is the width and L is the length)

Since the length is three times the width we can write:

L = 3w

We can substitue L with 3w:

Perimeter is equal to 98 so,

98 = 2w + 6w = 8w

W = 98/8

Therefore w is 12.25, and L is 36.75

  • <u>Kathy sells candles for $3 and flowers for $5. She plans to sell at least 200 items and likes to earn a minimum of $2500. </u>

Answer:

\left\{\begin{matrix}x + y = 200\\ 3x + 5y = 2500\end{matrix}\right

Step-by-step explanation:

<u>System of equations</u>

Kathy sells candles for $3 and flowers for $5. Let's set the following variables:

x = number of candles Kathy sells

y = number of flowers Kathy sells

She plans to sell 200 items, thus:

x + y = 200

She also likes to earn $2,500. The equation for this condition is:

3x + 5y = 2500

The system of equations is

\left\{\begin{matrix}x + y = 200\\ 3x + 5y = 2500\end{matrix}\right

11. x = 10, so DCE is 72. You get the measurement of x by adding 7x + 2 and x + 8 to equal 90. When you get x, you plug it in to the equation for DCE.

12. x = 17. KNM is 131. Get the measurement of x by adding both equations again, this time equaling it to 180 since it is a straight line and doesn't have a right angle. Plug in the x to the equation for KNM.
