Ms. Carger has has to send some emails in the afternoon. It takes her 3 minutes to start up her computer and log-in to her email, and then each email takes her 7 minutes to write and send. Write an equation to represent the number of emails she can send in x minutes.

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

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
