First set the equation equal to 0 by subtracting n from both sides.

That leaves us with 8n² - 11n = 0.

Since the GCF on the left is n, we can

factor it out to get n(8n - 11) = 0.

So either n = 0 or 8n - 11 = 0.

Solving for n in the second equation, we get n = 11/8.

So our solution is {0, 11/8}.

Answer:

False

Step-by-step explanation:

Using the rule of exponents

$a^{m}$ × $a^{n}$ ⇔ $a^{(m+n)}$ , then

$10^{3}$ × $10^{14}$ = $10^{(3+14)}$ = $10^{27}$

Nolan Walker decided to buy a used snowmobile since his credit union was offering such low interest rates. He borrowed $2,700 at

Lapatulllka [165]

He pays in interest of $111.0375. Interest is calculated in the two ways, by compounding or by simple interest.

<h3>How to calculate simple interest amount?</h3>

If the initial amount (also called as principal amount) is P, and the interest rate is R % annually, and it is left for T years for that simple interest, then the interest amount earned is given by:

$I = \dfrac{P \times R \times T}{100}$

The given data in the problem is;

The principal is,P=$2700

The rate of interest = 3.5%

The total time interval is,T

The total time interval is;

$\rm T= 5+365+31+21\ days$

The simple interest is found as;

$\rm SI = P \times R \times T \\\\ \rm SI = 2700 \times 0.0035 \times 1.172222 \\\\ SI=111.0375$

Hence, he pays in interest of $111.0375.

What is the value of n in the equation below? 12^n/12^5=12^4

Flura [38]

12^n
------- = 12^4
12^5

Let's clear out the fraction. To do this, mult. both sides by 12^5:

12^n = (12^4)(12^5) = 12^9 Then n = 9 (answer)
