Which is the solution set of the compound inequality 3.5x - 10 > -3 and 8x - 9 < 39

ludmilkaskok [199]

Hello! So, for the first inequality, we have to add 10 to both sides. When you do that, 3.5x > 7. Then, you have to divide both sides by 3.5. When you do that, you get x > 2. Then, for the second inequality, you have to add 9 to both sides, then you would get 8x < 48. Divide both sides by 8 and you get x < 6. The compound inequality for this question would be 2 < x < 6.

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.
