A hmie nedds dis rn iight thxs for yall hel For the following system, if you isolated x in the second equation to use the Substitution Method, what expression would you substitute into the first equation? (5 points)

3x + y = 8
−x − 2y = −10

−2y + 10
2y + 10
2y − 10
−2y − 10

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.

i believe it is the square root of 122 because when you turn it on it's side, to where the 5 inches is on the bottom, it looks like it is the same length.
