Plug it in
7(4) + 8(5) which would be 28 + 40
Answer: 68
The value for x is 9 because:
7x +49 = 2x + 94
7x-2x=45
5x=45
x=45/5
x=9
Addition property of equality
Given the points H(6,7) and I(-7,-6).
If point G lies
of the way along line segment HI.
Therefore, we can say that the point G divides the line segment HI in the ratio 1:1.
So, by using the cross section formula we can determine the coordinates of point G.
For the given points say
and
divided is in the ratio
, the coordinates are 
Coordinates G = 
= (-0.5 , 0.5)
Hence, the coordinates of G are (-0.5 , 0.5).
So, Santiago argues that point G is located at the origin. The point G is located at (-0.5, 0.5). Therefore, he is not correct.
