<u>Given the following data:</u>
- Combine time = 4 hours
- Sue's time = 10 hours
- Jeff's time = 12 hours
To calculate the number of time it would take Todd to paint the room alone:
How to solve a word problem:
In order to solve this exercise, we would first of all calculate their individual rate and combined rate respectively. Finally, we would add their individual rates together and equate it to the combined rate.
<u>For </u><u>Sue</u><u>:</u>
<u>For </u><u>Jeff</u><u>:</u>
<u>For </u><u>Todd</u><u>:</u>
<u>Combined rate:</u>
Adding the individual rates, we have:
Multiplying all through by 120t, we have:
t = 15 hours.

Step-by-step explanation:
For the upper left angle, we know that they are supplementary, so we can find the first angle of the triangle by
For the bottom right angle, we know that they are supplementary, so we can find that angle by
As a triangle has 180 degrees, we can subtract the values of the other two angles to find the final upper right angle.
Lastly, The upper right angle and x are supplementary so we can find x by subtracting the angle from 180
