The inequality to show the number of questions the teacher can include is 2x + 3.5x < 45
An inequality shows the relationship between two mathematical expressions. The first step to write an inequality is to identify the factors to consider. In this case:
- Time for multiple-choice questions: 2 minutes.
- Time for short-answer questions: 3.5 minutes.
- Total time for the test: 45 minutes.
Now, using this information you can create the inequality:
- 2x (multiple-choice questions time) + 3.5x (short-answer questions time) < 45 minutes (Total time for the test)
- x represents number of questions.
You can also solve this equality:
- 2x + 3.5 x < 45
- 5.5 x < 45
- x < 45 / 5.5.
- x < 8.1
This means the teacher can include 8 questions of each type.

Answer:
hot dog with visible grill marks
Explanation:
According to an article in the Los Angeles Times, citing University of California research published in the journal Cancer Causes and Control, people who eat 12 or more hot dogs a month are 9 times more likely to develop cancer. This is because the hot dog sausage is a processed meat that can influence the onset of cancer in the body.
To understand this, it first needs to be clarified that processed meat is a food that goes through a long preservation process to extend its shelf life and enhance flavor. Roughly speaking, this is equivalent to stating that it is a fresh product of animal origin that is processed, changing color and texture, for example. It is also important to say that there is no conservation method (brine, smoking etc.) that offers less risk. In addition, these meats may receive additives in addition to salt, such as color-fixing compounds (nitrate), which are unhealthy and stimulate cancer.

Exercise and not to smoke or be around second hand smoke. But exercise is probably the more important thing you can do to protect your respiratory system.
Not too long but just enough so that your muscles can relax. I would say no less than 15 seconds but no more than 45 seconds
