Answer:
3.6 hours
Step-by-step explanation:
Blake can do work in hours = 9
Blake can do a part of work in 1 hour = 
Ned can paint the same room in six hours.
Ned can do a part of work in 1 hour = 
They can do a part of work together in 1 hour = 
= 
Now they can do part of work in hour = 1
So, they can do whole work in hours = 
= 
Hence it will take 3.6 hours to paint the room if they work together.
Hello from MrBillDoesMath!
Answer:
x = 10
Discussion:
A plane triangle contains 180 degrees. Adding the angles in the triangle shown in #8 gives
(4x + 7) + (3x + 13) + 90 = 180
Note the "right angle" shown in the triangle has been replaced by its 90 degree equivalent in the above equation.
Combining like terms gives
( 4x + 3x) + (7 + 13) + 90 = 180
7x + 20 + 90 = 180 => (subtract 90 from each side)
7x + 20 + 90 - 90 = 180 - 90 = 90 =>
7x +20 = 90 => (subtract 20 from each side)
7x + 20 -20 = 90 -20 =>
7x = 70 =>
x 70/7 =10.
Thank you,

Answer: In both options, you should play game number 1 with a winning mean score of 3.25 to 3.75.
To find the average when you roll a die, you need to about up all the values in the set and divide by the number of data points.
In this case, 1 + 2 + 3 + 4 + 5 + 6 = 21 / 6 = 3.5
Since the mean is 3.5, that is what you are most likely to average for your score. Regardless of the number of rolls, this is most likely. Therefore, select the first game.
