Answer: The mean of all the numbers is 41.

Step-by-step explanation:

To find the mean of a set of numbers you must first add them all together. In this case, all of the numbers added together equaled 205. Then, you divide what ever your previous number was by how many numbers are in the original set all total. In this case, there was 5. So my last step would be dividing 205 / 5 = 41. 41 is my final answer.

Answer:

3 = x

Step-by-step explanation:

0 > 3x - 3 - 6

You want to group up the -3 and -6 first

0 > 3x - 9

Then you want to add 9 to each side to cancel out the negative 9 on one side.

0 > 3x - 9

+9 +9

9 > 3x

Now you just divide by 3 on each side

$\frac{9 = 3x}{3}$

3 = x

Write an equation that relates the angle in a triangle. The measure of angle A is 45 degrees. The measure of angle B is b degree

Korolek [52]

Since the interior angles of a triangle equal 180°, then 180-45=135.

Then you would use 135 to find the remaining two angles: b+3b=135.
4b=135.

Divide to find b. And the plug in whatever b is for the to figure out Angles B and C.

However, I believe the equation it's looking for is: 180=45+b+3b OR 45+4b=180
