<h3>Solution : </h3>

Let us first solve the value of x in the square .

3x + 1 + 3x + 1 + 3x + 1 + 3x + 1

= 12x + 4 = 2x + x + 8 + 4x + 2

= 12x + 4 = 7x + 8 + 2

Step 1: Simplify both sides of the equation.

12 x + 4 =7x + 8 + 2

12x + 4 = (7x)+(8+2)(Combine Like Terms)

12x+4=7x+10

Step 2: Subtract 7x from both sides.

12x+4−7x=7x+10−7x

5x+4=10

Step 3: Subtract 4 from both sides.

5x+4−4=10−4

5x=6

Step 4: Divide both sides by 5.

5x / 5 = 6/5

x=6/5

4-58. Lisa plans to retire on her 61st birthday. On her

mojhsa [17]

Answer:

Lisa invest "$2180.81" in her bank.

Step-by-step explanation:

The given values are:

On Lisa's 62nd birthday,

she withdraw = $10,000

The annuity of $A will remain at 3 percent for 40 years. The retirement pension of $10000 lasts 23 years at rate percentage of 3 but begins 40 years later.

⇒ $A\times (\frac{P}{A} ,3 \ percent,40) - 10000 (\frac{P}{A} ,3 \ percent,23)\times \frac{1}{(1.03)40} = 0$

⇒ $A\times 23.1148 - 10000\times 16.4436\times 0.3066 = 0$

⇒ $A = 10000\times 16.4436\times \frac{0.3066}{23.1148}$

⇒ $= 10000\times 16.4436\times 0.0132$

⇒ $=2180.81$ ($)

A scale drawing of a square has a side length of 6 millimeters. The drawing has a scale of 1 mm : 7 km. Find the actual perimete

zvonat [6]

Answer:

The real perimeter is:

$P= 24 mm *\frac{7 km}{1mm}= 168 km$

And the area would be:

$P = 36mm^2 *\frac{(7km)^2}{(1mm)^2} = 1764 km^2$

Step-by-step explanation:

For this case we know one side of a square given 6mm.

We can begin calculating the perimeter for the scale figure with this formula:

$P = 4x = 4*6 mm =24 mm$

The area for this case is given by:

$A = x^2 = 6mm^2 = 36 mm^2$

And we know that the drawing has a scale of 1 mm : 7 km and if we convert the perimeter to km we got:

$P= 24 mm *\frac{7 km}{1mm}= 168 km$

And the area would be:

$P = 36mm^2 *\frac{(7km)^2}{(1mm)^2} = 1764 km^2$
