Answer: 33 years

Step-by-step explanation:

Because 3% divided by a thousand is 0.03.

We can multiply that by the amount to get the total obtained by year.

0.03 x 12000 = 360

Now 12000 ÷ 360 = 33.3333...

So, 33 years.

We can also use the simple interest formula:

I = prt

I = interest

P = investment

R = interest rate

T = time

24000 = (12000) x (0.03) x T

T = 66.67

It would take 66 years for the interests gaining to reach 24000$, BUT we had 12000$ already, so if we divide 66.67 ÷ 2 = 33.33..

In 33 years we would have 12000$ + the main 12000$ so around 24000$ (should be more than 24k)

How to get everything to one side of the inequality for 3+4/x>=(x+2)/x

Ksenya-84 [330]

Answer:

$2x+2\geq 0$

Step-by-step explanation:

Given:

The given inequality is.

$3+\frac{4}{x} \geq \frac{x+2}{x}$

Solution:

Simplify the given expression.

$3+\frac{4}{x} \geq \frac{x+2}{x}$

Multiply by x both side of the equation.

$x(3+\frac{4}{x}) \geq x(\frac{x+2}{x})$

Simplify.

$3x+\frac{4x}{x} \geq x(\frac{x+2}{x})$

$3x+4\geq x+2$

Rewrite the equation as.

$3x+4-x-2\geq 0$

$2x+2\geq 0$

Therefore, $2x+2\geq 0$ is the simplest form of the given expression.
