I believe it is 8,000 grams :).
Answer: 100
set up equation: GHE+EHI=GHI
(x+38)+(x+104)=134
calculate
you get x= -4
put -4 into EHI
(-4)+104= 100
9t-6-6t=6 -- add 6 to both sides
9t-6t=12 -- combine like terms
3t=12 -- divide by 3
t=4
For the first question, simply find a point that is on the line segment. For the second question, knowing that in quadrant iii the x values are negative and the y values are also positive using this fact find the point that has x negative and y positive.
