Answer:
The correct answer is:
- <u>30 = 10 + 3(h - 2)</u>
<u>30 = 10 + 3h - 6</u>
<u>26 = 3h</u>
<u>h = 8.67</u>
Step-by-step explanation:
We're gonna calculate by our part the hours a new costumer can rent a bike and pay a total of $30, using the original function:
Where:
- <em>f (h) = Total cost.
</em>
- <em>h = the number of hours.</em>
We know The total money spent must be $30, by this reason, the function change to:
- <u>30 = 10 + 3(h - 2)</u>
Now, we must clear the h variable, by this reason, we multiply 3 by h and 2:
- 30 = 10 + 3*h - 3*2
- <u>30 = 10 + 3h - 6</u>
We pass the 10 and the -6 to the left side of the equality:
- 30 - 10 + 6 = 3h (Remember to change the signs when you do this step)
- <u>26 = 3h</u>
Finally, we pass the 3 to the left side of the equality:
26 / 3 = h (the 3 pass to divide because is multiplying the x)
If we just use two decimals, the number of hours is:
How the third option is the one that shows this calculation and result, that is the correct answer.

Answer:
3.3
Step-by-step explanation:
Because √11 cannot be re-written as the ratio of two integers, it's irrational.
Using a calculator, we find that √11 = 3.3166. We must round this off to the nearest tenths place: 3.3.
