8 X
----- = ------
20 40000
40000/20=2000
2000*8=16000
X=16000
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.

Hope this helps!
Answer:
26
Step-by-step explanation:
f(x)=x^2+5x g(x)=5‒x
f(3)=3^2+5(3) g(3)=5‒3
f(3)=9+15 g(3)=2
f(3)=24
f(3)+g(3)=24+2
=26
i think it is easy to understand &i hope it helps you
Answer:
1100 minutes
Step-by-step explanation:
Equation: 35=.05x-20
Why? x is the amount of minutes on his phone. Each minute is 0.05 hence 0.05x. Subtract 20 because that is the flat rate
55=.05x
x=1100
Therefore he was on his phone for 1100 minutes
