Answer:

The third side has a length of 9

Step-by-step explanation:

The two sides of equal length can be represented as x, and x

The thirds side is five less that twice the length of the other sides can be represented as  2x - 5.

The perimeter is 23, so the sum of all 3 sides is 23, now we have..

x + x + 2x - 5 = 23          solve for x...

4x = 28

x = 7,

so two sides are 7, and 7, and the third side is

2(7) - 5

  14 - 5

   9

A rectangular garden is 15 feet wide. If its area is 1050ft², what is the length of the garden?
joja [24]

The width is w=15 ft.

The area is A=1050 sq ft.

The length of the garden is,

\begin{gathered} L=\frac{A}{w} \\ =\frac{1050ft^2}{15ft} \\ =70ft \end{gathered}

Thus, the length of the garden is 70 ft.

4x-12y= 13<br> 32y+14x=13
Kazeer [188]

Answer:

(143/74, -65/148)

Step-by-step explanation:

We have the equations:

4x - 12y = 13

14x + 32y = 13

Let's use elimination, so multiply the first equation by 8 and the second equation by 3:

8 * (4x - 12y = 13)  ⇒  32x - 96y = 104

3 * (14x + 32y = 13)  ⇒  42x + 96y = 39

Add those two equations:

    32x - 96y = 104

+   42x + 96y = 39

________________

    74x  +  0y  =  143

Divide both sides by 74:

x = 143/74

Plug this into an equation to find y:

4x - 12y = 13

4 * (143/74) - 12y = 13

12y = 572/74 - 13 = -390/74

y = -65/148

The answer is (143/74, -65/148).
