x=9
Step-by-step explanation:
logx (531441) = 6
Changing this to an exponential
x^6 =531441
Take the 6th root of each side
(x^6)^1/6 = (531441)^1/6
x =9
Answer:
Ms. Carger would have sent
emails in x minutes
Step-by-step explanation:
Firstly, Ms. Carger takes her 3 minutes to start up her computer and log-in to her email.
Therefore in x minutes, after starting up her computer and logging-in to her email, she would have x minutes minus the time used to start up her computer and log-in to her email. this implies she would have (x-3) minutes left for sending emails.
Since it takes 7 minutes to write and send each email, in (x-3) minutes she would be able to send only
emails.
Therefore equation to represent the number of emails she can send in x minutes is
emails
In PEMDAS you do parentheses first
(32-20) equals 12
Now you divide
12/4 equals 3
The answer is 3
