Answer: Josh = 19.8 hours, Danny = 10.8 hours
<u>Step-by-step explanation:</u>


Since time cannot be negative, x=-5.8 is an extraneous solution (not valid) so x = 10.8
Josh: x + 9 --> 10.8 + 9 = 19.8
Danny: x --> 10.8

2a) k = 9.45 & 0.55
2b) x = 3/2
2c) x = 2/3 <em>(x = -1 is an extraneous solution so is not valid)</em>
2d) No Solution <em>(x = 1 is an extraneous solution so is not valid)</em>
Here is the work for 2a. Follow this format for b, c, & d


The area of number four, the hexagon, is 841.78.
Hope this helps!
Answer:
We know that the sum of the the interior angles of a quadrilateral is 360°.
In the figure, angle H = angle F
angle H+ angle F+ angle E+ angle G =360°

Therefore, <em><u>Angle F = 121°.</u></em>
Answer: 68 1/18
Step-by-step explanation:
Area of the large rectangle:
11 1/3 x 7 = 79 1/3
Area of tiled floor:
4 5/6 x 2 1/3 = 11 5/18
79 1/3 - 11 5/18 = 68 1/18
