The length of a rectangular boat storage shed must be 4 meters more than the width, and the perimeter must be at least 112 meter

ludmilkaskok [199]

Answer:

The width of the rectangular shed can be 26, 27, 28, ........

Step-by-step explanation:

Let the width of the rectangular shed be, W = x

Then the length of the rectangular shed will be

L = 4 + width

L = 4+x

We know that the perimeter of the rectangle is 2W+2L

Also it is given that the perimeter of the rectangular must be at least 112 meters

2W+2L >= 112

Substituting the values

$2x+4x+8 \geq 112$

$2x+8+2x \geq 112$

$4x+8 \geq 112$

$4x \geq 112-8$

4x>104

$x \geq \frac{104}{4}$

$x \geq 26$

0.15(y-0.2)=2-0.5(1-y)<br><br> The answer is -153/35 I just need to know how to get that

butalik [34]

Answer:

$y=-\dfrac{153}{35}$ .

Step-by-step explanation:

The given equation is

$0.15(y-0.2)=2-0.5(1-y)$

Using distributive property, we get

$0.15(y)+0.15(-0.2)=2-0.5(1)-0.5(-y)$

$0.15y-0.03=2-0.5+0.5y$

$0.15y-0.03=1.5+0.5y$

Isolate variable terms.

$0.15y-0.5y=1.5+0.03$

$-0.35y=1.53$

Divide both sides by -0.35.

$y=\dfrac{1.53}{-0.35}$

$y=-\dfrac{1.53}{0.35}\times \dfrac{100}{100}$

$y=-\dfrac{153}{35}$

Therefore, $y=-\dfrac{153}{35}$ .
