Answer:
Step-by-step explanation:
Start by combing the terms on the right. 3b - 8 = 3b - 2 because 7b - 4b is going to equal 3b
You are now officially stuck. The moment you try and put the 3b's on the same side of the equation, they will cancel out. There is no unique solution.
Explanation:
<em>What is an eighth of 32?
</em>
An eighth of 32 means 32 is divided into eight equal parts.
Let's use a fact family for this problem:
8 * ? = 32
32 / 8 = ?
-------------
8 * 4 = 32
32 / 8 = 4
An eighth of 32 is 4.
Five eights of 32:
Five eighths of 32 is five times four which is 20
20 is 5 eighths of 32
5/8 * 32 = 20
32 * 5 / 8 = 20
The answer is 32.

Explanation:
The number of times the 6-sided number cube will be rolled will is
![750](https://tex.z-dn.net/?f=750)
Let the numbers greater than 4 be represented below as
![E_1](https://tex.z-dn.net/?f=E_1)
![\begin{gathered} E_1=\lbrace5,6\rbrace \\ n(E_1)=2 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20E_1%3D%5Clbrace5%2C6%5Crbrace%20%5C%5C%20n%28E_1%29%3D2%20%5Cend%7Bgathered%7D)
The number of sample space will be
![n(S)=6](https://tex.z-dn.net/?f=n%28S%29%3D6)
The probability of rolling a number greater than 4 will be calculated below as
![\begin{gathered} Pr(E_1)=\frac{n(E_1)}{n(S)} \\ Pr(E_1)=\frac{2}{6}=\frac{1}{3} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20Pr%28E_1%29%3D%5Cfrac%7Bn%28E_1%29%7D%7Bn%28S%29%7D%20%5C%5C%20Pr%28E_1%29%3D%5Cfrac%7B2%7D%7B6%7D%3D%5Cfrac%7B1%7D%7B3%7D%20%5Cend%7Bgathered%7D)
Hence,
To calculate the number of times a number greater than 4 will be rolled will be calculated below as
![\begin{gathered} =Pr(E_1)\times750 \\ =\frac{1}{3}\times750 \\ =250times \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%3DPr%28E_1%29%5Ctimes750%20%5C%5C%20%3D%5Cfrac%7B1%7D%7B3%7D%5Ctimes750%20%5C%5C%20%3D250times%20%5Cend%7Bgathered%7D)
Hence,
The final answer is
