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.

Burn-injury patients should be monitored for their blood pressure (low bp), heart rate (tachycardia) and urine output. The best indicative factor for a good resuscitative fluid therapy is urine output. Which is 0.5mL/kg in adults. A low urine output means that the patient is dehydrated.
