Answer:
x = 45
Step-by-step explanation:
The average is calculated as
average = 
here the average = 50 , thus
= 50
Multiply both sides by 4
36 + 44 + 75 + x = 200
155 + x = 200 ( subtract 155 from both sides )
x = 45
The correct answer is B) m=-8
First, add 9 on both sides of the equation. You should end up with 4m=-32.
Next, divide both sides of the equation by 4. You should end up with m=-8. (A negative divided by a positive equals a negative)
Hope this helps! Have a great day ;)
You can't simplify it because no whole number will go equally into 7
