10(x/2+6)=8
10(x/2+6/1)=8
10x/2+60/1=8
5x=8-60
5x=-52
5x/5=-52/5
x=-10.4
so you can test if the answer is correct by putting x=-10.4 back into the original equation. if you'll get 8 as your answer, then the solution is correct.

You roll a 6-sided die.<br> What is P(prime)?<br><br> Write your answer as a percentage.

posledela

$\huge \underline\text {Hello There!!}$

<h3><u>Given</u></h3>

Rolled A six-sided dice.

P(Prime) as percentage

<h3><u>Solution</u></h3>

Total Possible Outcomes= 1, 2, 3, 4, 5, 6.

So, No. of possible Outcomes= 6

Prime number of the dice= 2, 3, 5

So, No. of favorable outcomes of Prime number= 3

$\text{Probability of an event= }$

$\frac{ \text{favorable no. of outcome}}{ \text{total no. of outcome}} \times 100$

$\text{Percentage of Probability getting P(Prime) number on face of dice} =$

$\frac{3}{6} \times 100 \\ \\ = \cancel \frac{3}{6} \times 100 \\ \\ = \frac{1}{ \cancel2} \times \cancel{100} \\ \\ = 50\%$

$\therefore \% \text{ Probability of getting prime number is \red{50} \red\%}$
