Answer:

x = 16

Step-by-step explanation:

Since the lines are ||, the angles are each the same. This means that the equation has to look like this:

7x + 9 = 9x - 23

From there even out the sides, subtracting/ adding to one side what you do to the other:

7x +9 = 9x -23

-7x +23 -7x +23

0 32 = 2x 0

32 = 2x

Then divide each side by 2

Your answer is x = 16

brainliest is always appreciated*

I need someone to solve this problem for me please

First, solve the area of the entire large rectangle (28)(45) = 1260
Next, find the area of the chunk that is cut out (11)(15) = 165
- we know the width is 15 because 45 - 6 - 24
Subtract the cut out piece from the overall rectangle 1260 - 165 = 1095

How long will it take for an investment to triple if it is compounded continuously at 12%

myrzilka [38]

Answer:

9.694 years

Step-by-step explanation:

Let the investment is $P.

So, we are asked to determine the time it will grow to triple with the compound interest rate of 12%.

Let the time is y years.

So, from the formula of compound interest we can write

$3P = P(1 + \frac{12}{100} )^{y}$

⇒ $(1 + \frac{12}{100} )^{y} = 3$

⇒ $(1.12)^{y} = 3$

Now, taking log both sides we get,

y log 1.12 = log 3 {Since, $\log a^{b} = b \log a$ }

⇒ 0.04922y = 0.477712

⇒ y = 9.694 years (Answer)
