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:
√113 and in the decimal form it's 10.630

Answer:
Unit rate in metric tons per hour = 1.17
Explanation:
A construction company can remove 5 1/4 metric tons of dirt from a construction site in 4 1/2 hours.
Dirt removed
Time taken in hours
Unit rate in metric tons per hour = Dirt removed in metric tons/ Time taken in hours for that.
Unit rate in metric tons per hour is 1.17 metric tons.
18m/3hrs = 6m/hr
Multiply the rate by the time:
(6m/hr)(3/4hr)
6 time 3/4 gives you 4.5, or 9/2; the hours cancel, leaving you with:
4.5 miles, or as a fraction 9/2 miles, or, as a mixed number, 4 1/2 miles. (whichever way they want it.)
Hope this helps!
The correct answer is $9.01
24 - (10.91 + 4.01)
24 - 14.99 = $9.01
