An architect designs a rectangular flower garden such that the width is exactly​ two-thirds of the length. If 310 feet of antiqu
Alona [7]

The length and width of the garden are 93 feet and 62 feet respectively.

<u><em>Explanation</em></u>

Suppose, the length of the rectangular garden is x feet.

As the width is exactly​ two-thirds of the length, so the width of the garden will be: \frac{2x}{3} feet.

310 feet of antique picket fencing are to be used to enclose the​ garden. It means, <u>the perimeter of the garden is 310 feet</u>.

<u>Formula for perimeter of rectangle</u> = 2(length+width)

So, the equation will be....

2(x+\frac{2x}{3})= 310\\ \\ x+\frac{2x}{3}= \frac{310}{2}\\ \\ \frac{5x}{3}=155\\ \\ 5x= 465\\ \\ x= \frac{465}{5}=93

So, the length of the garden is 93 feet and the width is (\frac{2*93}{3})=62 feet.

Find the ordered pairs for the x- and y-intercepts of the equation 3x − 2y = 18 and select the appropriate option below.
olasank [31]
<h2>Greetings!</h2>

Answer:

B)

Step-by-step explanation:

Y intercept:

Simply substitute all the x values with 0:

When x = 0:

3(0) - 2y = 18

Move the - 2y over to the other side making it a +2y:

0 = 18 + 2y

Move the +18 over to the other side making it a -18:

-18 = 2y

Divide both sides by 2:

\frac{-18}{2} = \frac{2y}{2}

-9 = y

So y intercept is:

<h3> (0 , -9)</h3>

X - intercept:

Simply substitute all the Y's with 0:

3x - 3(0) = 18

3x = 18

Divide both sides by 3:

\frac{3x}{3}  = \frac{18}{3}

x = 6

So the X intercept is:

<h3>(6 , 0)</h3>

This means that your guess of B is correct.
