We can put the two equations together with substitution, and we get
3x + 2y = 30
Now we have a single equation in two variables, so we don't have enough information to solve for both x and y.
Answer:
its a square, so all sides similar
28. SV = RT/2 = 5.7/2 = 2.8
29. RT^2 = RQ^2 + QT^2
--> RT = √
(4^2 + 4^2)
RT = √32 =5.7
30. perimeter of RVS = 2.8 + 2.8 + 4 = 9.7
