Answer:

x=45

Step-by-step explanation:

To find x isolate the variables by using the properties of equality. First, subtract 8 from both sides, $\frac{x}{3} = 15$ . Then multiply both sides by 3, $x=45$ . Finally, to check you can plug 45 back into the equation, $\frac{45}{3} +8=23$ . Next, solve this equation and get 23=23, since this is a true statement 45 is correct.

Hello! The answer should be B: 6i $\sqrt{6$ . Since the square root is above a negative, an imaginary number would come out. Because of this, you can easily recognize that it would be B.
However, if you can't, you could use the calculator to check (ignoring the negatives), 6 $\sqrt{6$ is equal to $\sqrt{216}$ .
The final answer should be B.

<h2>Answer:</h2>

Prediction for the number of unsuccessful rolls is 15.

<h2>Step-by-step explanation:</h2>

There is $\frac{1}{6}$ chance of rolling number 6 on the cube. If we want to find out what is the prediction for rolling number 6 in 18 rolls, we need to multiply $6*\frac{1}{6}$ which is 3. So if we roll a cube 18 times, we will probably got number 6 three times. When we subtract 3 from 18 (18-3), we get 15. That is the answer to your question.
