The first thing we must do is remove the log. In this case, the base of this log is 10, which means that we must have each side of this equation have a base of 10.
This gives us
The base 10 and the log will cancel out to give us
Then we can solve for t

Answer:
Step-by-step explanation:
Quiana has 5 times more text messages from Yolanda than from Pierre, we also know that she actually has 30 text messages from Yolanda. In other words, 30 texts from Yolanda is 5 times more text messages than from Pierre.
Thus, if we call p the number of texts messages from Pierre we would have that
(since 30 texts from Yolanda is 5 times more than p, we can divide by 5 to find p)
And if we solve this equation we would get that Quiana has 6 text messages from Pierre
