sukhopar [10]

Answer:

0.42 ft

0.92 ft

Step-by-step explanation:

Width of mural on painting = 5 inches

Height of mural on painting = 11 inches

12 inches of the painting represents 1 foot of the mural

1 inch of the painting represenets $\dfrac{1}{12}$ foot of the mural.

$5\ \text{inches}=5\times \dfrac{1}{12}=0.42\ \text{ft}$

$11\ \text{inches}=11\times\dfrac{1}{12}=0.92\ \text{ft}$

The width of the mural is 0.42 ft and height of the mural is 0.92 ft.

Answer:

$(10, 0)$

Step-by-step explanation:

Let's try all the options:

$\left \{ {{2x + y = 20} \atop {4x-2y = 40} \right.$

Considering $(10, 0)$ :

$$\left \{ {{2(10) + 0 = 20} \atop {4(10)-2(0) = 40} \right. $\\$

$\left \{ {{20 + 0 = 20} \atop {40-0 = 40} \right.$

$\left \{ {{20= 20} \atop {40 = 40} \right.$

Considering $(0, 10)$ :

$$\left \{ {{2(0) + 10 = 20} \atop {4(0)-2(10) = 40} \right. $\\$

$\left \{ {{0 + 10 = 20} \atop {0-20 = 40} \right.$

$\left \{ {{10= 20} \atop {-20 = 40} \right.$

$\left \{ {{10\neq 20} \atop {-20 \neq 40} \right.$

Considering $(4, 2)$ :

$$\left \{ {{2(4) + 2 = 20} \atop {4(4)-2(2) = 40} \right. $\\$

$\left \{ {{8 + 2 = 20} \atop {8-4 = 40} \right.$

$\left \{ {{10= 20} \atop {4 = 40} \right.$

$\left \{ {{10\neq 20} \atop {4 \neq 40} \right.$

Considering $(10, -10)$ :

$$\left \{ {{2(10) -10 = 20} \atop {4(10)-2(-10) = 40} \right. $\\$

$\left \{ {{20 -10 = 20} \atop {40+20 = 40} \right.$

$\left \{ {{10= 20} \atop {60 = 40} \right.$

$\left \{ {{10\neq 20} \atop {60 \neq 40} \right.$
