Si el largo del macizo de flores es (x +3) el ancho es (2x -3) y el perímetro es 30 pies,cual es el valor de x

Dafna11 [192]

Answer:

x = 48.62

Step-by-step explanation

Perímetro = diámetro/pi

(2x - 3)/pi = 30 pies

2x - 3 = 30 * pi

2x - 3 = 94.25

2x = 94.25 +3

x = 97.2/2

x = 48.6

G>=5, so anything above or equal to 5 would count. So, you could use 5, 6, 7.

Solve the system, or show that it has no solution. (If there is no solution, enter NO SOLUTION. If there are an infinite number

liberstina [14]

Answer:

The system has an infinite set of solutions $(x,y) = (x, \frac{x-5}{4})$

Step-by-step explanation:

From the first equation:

$20x - 80y = 100$

$20x = 100 + 80y$

$x = \frac{100 + 80y}{20}$

$x = 5 + 4y$

Replacing on the second equation:

$-14x + 56y = -70$

$-14(5 + 4y) + 56y = -70$

$-70 - 56y + 56y = -70$

$0 = 0$

This means that the system has an infinite number of solutions, considering:

$x = 5 + 4y$

$4y = x - 5$

$y = \frac{x - 5}{4}$

The system has an infinite set of solutions $(x,y) = (x, \frac{x-5}{4})$
