Answer:
CF is a diagonal through the interior of the cube.
The solution to the given system of equation is (3, 3, 3)
<h3>Solving system of equations</h3>
Given the following system of equation expressed as:
2x-y+5z=16
X-6у +2z=-9
3x+4y- z=32
Multiply equation 2 by 2 to have:
2x-y+5z=16
2X-12у +4z=-18
Subtract
10y+z = 34 .........4
Similarly
3X-18у +6z=-27
3x+4y- z=32
Subtract
-22y+7z = -59 ........... 5
Equate 4 and 5
10y+z = 34 .........4 * 7
-22y+7z = -59 ........... 5 * 1
_______________________
70y+7z = 238
-22y+7z = -59
Subtract
92y = 297
y = 3
Recall that
10y+z = 34
10(3) + z = 34
z = 3
Since x - 6y +2z = -9
x-6(3)+2(3) = -9
x - 18 + 6 = -9
x = 3
Hence the solution to the given system of equation is (3, 3, 3)

Answer:
In scientific notation, that would be;
7.0 * 10^-7 m
Step-by-step explanation:
Here, we want to write the given diameter in scientific notation
Mathematically, that can be done by moving the decimal point to the back of 7
The number of times we move will be counted as negative powers of 10 host
Thus, we have;
7.0 * 10^-7
Well, if the 3 dentists saw 51 patients and they saw a somewhat equal amount, you would have to do 51 divided by 3 and round to the nearest first.
