Answer:
1.5 hours
Step-by-step explanation:
there are 6 hours in between the times of 4 and 10
so 4 sister split up 6 hours equally
to do this, we divide 6 and 4
6/4 = 1.5 hours
each sister can spend 1.5 hours on the computer
√102 = 10.09950494.....
So 10.09950494..... to the nearest tenth would be 10.10, because 9 comes AFTER 5 so we will go to the next number which would make the number 10.10.
SO, √102 ≈ 10.10.
Hope I helped ya!!!☺☺☺☺
Answer:
x = 27
Step-by-step explanation:
4(x−9)=4(9+1/3x).
Divide each side by 4
(x−9)=(9+1/3x)
Subtract 1/3 x from each side
x - 1/3x -9 = 9+1/3x -1/3x
2/3x -9 = 9
Add 9 to each side
2/3x -9+9 = 9+9
2/3x = 18
Multiply each side by 3/2
3/2 * 2/3x = 18*3/2
x = 27

Hello!</h2>
The answer is:
The x-coordinate of the solution to the system of equations is:
<h2>
Why?</h2>
We can solve the problem writing both equations as a system of equations.
So, we are given the equations:
Then, solving by reduction we have:
Multiplying the first equation by 2 in order to reduce the variable "x", we have:
Now, substituting "y" into the first equation, to isolate "x" we have:
Hence we have that the x-coordinate of the solution to the system of equations is
Have a nice day!
