Answer:
Multiple the first equation by -1
Step-by-step explanation:
After doing this you add the two equations together and follow the systems of equations as normal

Therefore y = 2
Answer:
The length of the shorter base of the little trapezoid trail is 1 mi.
Step-by-step explanation:
Let the shorter base of the large trapezoid is S and the larger base of the large trapezoid is L.
Similarly, assume that the shorter base of the small trapezoid is s and the larger base of the small trapezoid is l.
Since, the trapezoids are similar, so

Now, given that S = 2 mi, L = 8 mi and l = 4 mi and we have to find s.
So,
mi. (Answer)
Answer:
15
Step-by-step explanation:
-a -8b = -9 + 24 = 15
