Can someone show me how to do these problems, please? I really need help... I just have to answer the questions and show how it was solved

1. Carlos spends at least 45 minutes each day on the Internet. Which inequality could be used to describe the amount of time, x, that Carlos spends on the Internet?


2. Amrita spends at most 2 hours watching television each night. Which inequality could be used to describe the amount of time, x, that Amrita spends watching television each night?


3. Joe expects to spend at least $8500 on a used car, but he can’t afford to spend more than $12,000. Which inequality could be used to describe the amount of money, x, that Joe may spend on a car?


4. Teenagers should sleep between 8 and 10 hours per night. Sarah typically sleeps 2 hours less than this per night. Which inequality describes the amount of time that Sarah sleeps?


5. Men need to intake between 2200 and 2800 calories daily. Women need 600 fewer calories than this. Write and solve an inequality to discover how many calories women should be taking in per day.

really? Just remember that
< means less than
<= means less than or equal, or not more than, or at most
> means greater than
>= means greater than or equal, or not less than, or at least

So, now you can easily see that

#1: x >= 45
#4: 8-2 <= x <= 10-2

try the others.
