Answer:

x=12

Step-by-step explanation:

you need the x alone so you substract 3 from both sides.

Then you have, -x= -12

You need the x positive so you change the sign for it but as it is an equation you need to do the same thing on the other side, making both sides positive.

x=12

The answer is B. 3 - x = -9
-x + 3 = -9
Subtract 3 from both sides of the equation. Simplify

The B option is correct.

<h2>Exponent</h2>

Exponential notation is the form of mathematical shorthand which allows us to write complicated expressions more succinctly. An exponent is a number or letter is called the base. It indicates that the base is to raise to a certain power. X is the base and n is the power.

Given

A number is -906,060.

The equivalent number of the given number.

<h3>How to find the equivalent number of the given number?</h3>

We know the number is -906,060.

It can be represented as $\rm -906,060 = -9.0606 \ times\ 10^5$ .

Thus, the B option is correct.

If you save $3,000 at an interest rate of

juin [17]

Amount earned in compound interest = P(1 + r)^n; where P is the principal, r is the rate and n is the number of periods.

Amount = 3,000(1 + 14%)^6 = 3,000(1 + 0.14)^6 = 3,000(1.14)^6 = $6,584.91
