Answer:
If they are not collinear, then the three points are coplanar.
Step-by-step explanation
Contrapositive is the negative + opposite of the original statement.
X + x + 24 = 58
x = (58-24)/2=17
the first number is 17 and the second number is the sum of 17 and 28. Finding it has been left as an exercise for the reader.
Since the question only asks for bagels, put the cream-cheese idea aside.
The total spent has to be less than $7 so an equation can be this: $0.75x<$7 where x is the number of bagels
38= Sum
2= GCF of 18 and 20
