Determine the number of real solutions for each system of equations.

ratio is 2 : 9

the answer is three

13.5 : 3

the diagram shows you   triangle def with de=4, df=9 and de≠df≠ef.

the sum of the lengths of two triangles' sides are always greater than the length of the third side:

substitute sides lengths:

then 5< ef< 13 (option 3 is true).

def is a scalene triangle with all sides of different lengths (option 5 is true, option 2 is false).

answer: correct choices are 1, 3 and 5

i   want to say the correct answer is 12,000 correct me if i'm wrong
