Answer:
Infinitely many solutions
Step-by-step explanation:
Given:
y= 2x+5
1/2y = x+5/2
Multiplying 2 with both sides will give:
2( 1/2y) = 2(x+5/2 )
y= 2x+5
As both the equations are similar with same slope m=2 and y-intercept= 5
thus the system of equation will have infinite solution. Graph will show single line.

Really, we don't need to use that much math--we can use logic instead. Since the two congruent sides must be longer than 30in, the total has to be greater than 60in (the longest side plus the congruent sides.) So for our answer, we want the smallest total that is above sixty, which in this case is 72.44in.
Hope I helped, and let me know if you have any questions :) I can explain the real math if you want, it was just unnecessary here.
Answer: -9 1/3 or -9.3333333
Step-by-step explanation: You would just have to divide those two numbers and then add the negative to your answer.
