What grade is this for by the way?
Given the equation:
![\log _2(7x)+\log _22=1](https://tex.z-dn.net/?f=%5Clog%20_2%287x%29%2B%5Clog%20_22%3D1)
As we know: log a + log b = log (ab)
So,
![\begin{gathered} \log _2(7x\cdot2)=1 \\ \log _2(14x)=\log _22 \\ \\ 14x=2 \\ x=\frac{2}{14} \\ \\ x=\frac{1}{7} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Clog%20_2%287x%5Ccdot2%29%3D1%20%5C%5C%20%5Clog%20_2%2814x%29%3D%5Clog%20_22%20%5C%5C%20%20%5C%5C%2014x%3D2%20%5C%5C%20x%3D%5Cfrac%7B2%7D%7B14%7D%20%5C%5C%20%20%5C%5C%20x%3D%5Cfrac%7B1%7D%7B7%7D%20%5Cend%7Bgathered%7D)
So, the answer will be x = 1/7
<span>If its Monday, the probability that tomorrow is Tuesday is certain, therefore the probability is 1.</span>
