The area of a rectangular mirror is 15 7 16 square feet. The width of the mirror is 3 1 4 feet. If there is a 5 foot tall space

Vlad1618 [11]

Given:

Area of rectangle = $15\dfrac{7}{16}$ sq. feet.

Width of the mirror = $3\dfrac{1}{4}$ feet.

To find:

Whether it will fit on the wall whose length is 5 foot.

Solution:

We know that, area of a rectangle is

$Area=length\times width$

$\dfrac{Area}{width}=length$

Substituting the given values, we get

$Length=\dfrac{15\dfrac{7}{16}}{3\dfrac{1}{4}}$

$Length=\dfrac{\dfrac{15\times 16+7}{16}}{\dfrac{3\times 4+1}{4}}$

$Length=\dfrac{\dfrac{240+7}{16}}{\dfrac{12+1}{4}}$

$Length=\dfrac{\dfrac{247}{16}}{\dfrac{13}{4}}$

$Length=\dfrac{247}{16}\times \dfrac{4}{13}$

$Length=4.75
$

So, length of mirror is 4.75 feet which is less than 5 feet.

Therefore, the mirror will fit on the wall.

For this case we must solve each of the equations proposed:

A) $-6 (2s-1) = 30$

We apply distributive property to the terms within parentheses:

$-12s + 6 = 30$

Subtracting 6 from both sides of the equation we have:

$-12s = 24$

Dividing between -12 on both sides of the equation:

$s = \frac {24} {- 12}s = -2$

B) $-3m = -5 (m-8)$

We apply distributive property to the terms within parentheses:

$-3m = -5m + 40$

We add 5m on both sides of the equation:

$2m = 40$

Dividing between 2 on both sides of the equation:

$m = \frac {40} {2}\\m = 20$

C) $7 (2-g) = 49$

We apply distributive property to the terms within parentheses:

$14-7g = 49$

We subtract 14 from both sides of the equation:

$-7g = 35$

Dividing between -7 on both sides of the equation:

$g = \frac {35} {- 7}\\g = -5$

D) - $7 (3w + 4) = 14$

We apply distributive property to the terms within parentheses:

$-21w-28 = 14$

We add 28 to both sides of the equation:

$-21w = 42$

Dividing between -21 on both sides of the equation:

$w = \frac {42} {- 21}\\w = -2$

Answer:

$s = -2\\m = 20\\g = -5\\w = -2$
