Part A: Find a rational number that is between 7.7 and 7.9. Explain why it is rational. (2 points)
8_murik_8 [283]
A rational number is any number that can be written as the ratio between two other numbers i.e. in the form \frac{a}{b}

Part A:
An easy choice that makes sense is 7.8, right in the middle. To prove that it's rational we need to write it as a ratio. In this case we have 7.8=\frac{78}{10}

Part B:
We need a number that can't be written as a ratio (because it neither terminates nor repeats). Some common ones are \sqrt{2}, e, \phi and \pi so it makes sense to try and use those to build our number. In this case \frac{11\sqrt{2}}{5}\approx7.78 works nicely.

Answer:

x = \frac{7}{5}

Step-by-step explanation:

To solve for x, we need to isolate it [get it alone on one side]

We should start by simplifying (combining the like-terms of our equation):

5 + 5 = 5x + 5 - 2

10 = 5x + 3

- 3         - 3        (subtract 3 from both sides to isolate x)

7 = 5x

÷5  ÷5   (divide both sides by 5 to find "1"x)

\frac{7}{5}=x  

So, x = \frac{7}{5}

(x = 7/5)

hope this helps!!
