Answer:
m = -5
Step-by-step explanation:
Simplify both sides of the equation.
4(m−2)=2(m−9)
(4)(m)+(4)(−2)=(2)(m)+(2)(−9)(Distribute)
4m+−8=2m+−18
4m−8=2m−18
Subtract 2m from both sides.
4m−8−2m=2m−18−2m
2m−8=−18
Add 8 to both sides.
2m−8+8=−18+8
2m=−10
Divide both sides by 2.
2m/2 = -10/2
m = -5
I'm assuming that x is part of the data set, and, with x, the mean equals 105. To find the value of x, you must add all the data values together to get 544+x (you still don't know what x equals). Then put 544+x over how many days values there are, including x (there are 6). You should have 544+x/6. Now, as this is how you would calculate the mean if you knew what x was equal to, you must set it equal to the mean, since you know what it is (105). You should now have 544+x/6 = 105. You have your equation set up--now you just have to solve it. I would multiply by 6 on both sides to get rid of the 6 on the left side. You would then have 544+x = 630. I would finally subtract 544 from both sides to get x = 86. Your final answer is x = 86.
