Answer:
2,3
Step-by-step explanation:
2x+1<8
2x<7
x<7/2 or x<3.5
So, the values for x that make this statement true are 2 and 3, because they're both less than 3.5.
A rational number is simply a term that can be expressed as a fraction. Otherwise, that is an irrational number. So, you can use a calculator to verify if the number is rational or not.
The key characteristic of an irrational number is when it contains a long line of decimal places. For example, the term π and the Euler's number e are irrational numbers. The exact values of π and e are 3.14159 and <span>2.71828182846, respectively. In reality, those decimal places go on a long way. Particularly, </span>π<span> has a total of 2.7 trillion digits. Numbers inside radicals or roots can also be irrational numbers. For example </span>√3 is irrational because it is equal to 1.732050808. However, not all radicals are irrational. For example √15.3664 is equal to 98/25 or 3.92. That is a rational number. So, therefore, use the calculator to know the exact value of the term to properly distinguish rational from irrational.
If 15 degrees in 2hrs then in 1hrs is 15(degrees)÷2(hrs) and that is 7.5 degrees
That makes 7.5 degrees per hour
