For what value of x will 55 and x have the mean (average) as 67? explain how you got your answer

X=79

Step-by-step explanation:

The answer can be found by finding the difference of 67 and 55 which would be 12, then adding 12 and 67 to get 79. I can do this because if 2 numbers are split equally between them, then adding an number to get one will get you the other. It may seem confusing, comment if you still need help.

step-by-step explanation:

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
