Shawna, Ryan, and Dominic ate a whole pizza. Shawna ate 1

mafiozo [28]

Answer:

$\frac{1}{6}$

Step-by-step explanation:

You need to add the amount Shawna & Ryan ate together, then subtract it from 1 to find the amount of pizza that was left for Dominic to eat.

$\frac{1}{3}$ + $\frac{1}{2}$ = ?

Make all the denominators the same to add fractions.

$\frac{1}{3}$ is $\frac{2}{6}$

$\frac{1}{2}$ is $\frac{3}{6}$

$\frac{2}{6}$ + $\frac{3}{6}$ = $\frac{5}{6}$

1 - $\frac{5}{6}$ = $\frac{1}{6}$

Wich number line represents the solution set for the 2x-6>6(x-2)+8

Fantom [35]

Well...
2x-6x>-12+8-6
-4x>-10
Attention! ">" change for "<" because we multiply both members for (-1)
x<10/4
It is the same to say (-infinite ; 10/4) or (-infinite ; 5/2) or (-infinite ; 2.5)
Good luck!

Un agricultor tiene un terreno cuadrado dedicado al cultivo de hortalizas. Para ampliarlo, quiere comprar el terreno adyacente,

Agata [3.3K]

Answer: 20 meters.

Step-by-step explanation:

The formula for calculate the area of a square is:

$A=s^2$

Where "s" is the side length of the square:

The formula for calculate the area of a rectangle is:

$A=lw$

Where "l" is the lenght and "w" is the width.

Based on the information provided, you know the sum of the areas of the square land and the adjacent land is 600 m². This is:

$A_1+A_2=600\\\\s^2+lw=600$

Knowing that the width of the adjacent land is 10 meters:

$s^2+10l=600$

Since the lenght of the adjacent land and the side lenght of his actual land are equal:

$l=s$

You can substitute this into $s^2+10l=600$ :

$s^2+10s=600\\\\s^2+10s-600=0$

Applying the Quadratic formula, you get:

$s=\frac{-b\±\sqrt{b^2-4ac} }{2a}\\\\s=\frac{-10\±\sqrt{(10)^2-4(1)(-600)} }{2(1)}\\\\s_1=20\\\\s_2=-30$

Since the side lenght cannot be negative, you can determine that this is:

$s=20\ m$
