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,
butalik [34]

Answer:

Ms. Carger would have sent \frac{x-3\\}{7} \\ 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 \frac{x-3}{7} emails.

Therefore equation to represent the number of emails she can send in x minutes is \frac{x-3}{7} emails

Answer:

The required equation is D=0.5(4)

Step-by-step explanation:

Consider the provided information.

Student on the cross-country team runs 30 minutes a day as a part of her training,

30 minutes = 0.5 hours

As we know Speed=\frac{Distance}{Time}

Let the distance she runs in miles, is represented by D, and her running speed, in miles per hour is represented by S.

Therefore, the required equation is: S=\frac{D}{0.5}

Part (A) At a constant speed of 4 miles per hour for the entire 30 minutes​.

Substitute S=4 in above equation.

4=\frac{D}{0.5}

D=0.5(4)

D=2

Hence, the required equation is D=0.5(4)
