Step-by-step explanation:
i think so u also dont know the que
Answer:
[1] x - 6y = 3
[2] x + 2y = 5
Graphic Representation of the Equations :
-6y + x = 3 2y + x = 5
Solve by Substitution :
// Solve equation [2] for the variable x
[2] x = -2y + 5
// Plug this in for variable x in equation [1]
[1] (-2y+5) - 6y = 3
[1] - 8y = -2
// Solve equation [1] for the variable y
[1] 8y = 2
[1] y = 1/4
// By now we know this much :
x = -2y+5
y = 1/4
// Use the y value to solve for x
x = -2(1/4)+5 = 9/2
Solution :
{x,y} = {9/2,1/4}
<u>Answer</u>: 12.5 cm or 125 mm
<u>Explanation:</u>
Given: 
Conversion:
1 cm --> 10 mm
12.5 cm --> ( 12.5 * 10 ) mm
12.5 cm --> 125 mm
The centroid is found by intersecting the medians of a triangle
Answer: Choice B
This is something to memorize or have on a reference sheet
Side notes:
1) The altitudes cross to form the orthocenter
2) The perpendicular bisectors intersect at the circumcenter
3) The angle bisectors intersect at the incenter
