Answer: x: 25
y: 19
Step-by-step explanation:
find X: 2x +10 = 180/3
2x=50
x=25
Find Y
3y+3= 60
3y = 57
y = 57/3
y= 19
A)
x = # of students in math class

Sorry if it's hard to read. I tried my best. Hope I helped.
Answer:
- Timmy has successfully shown Suzie's conjecture is incorrect
- Suzie's conjecture is correct if the smallest square in the sum is 1
Step-by-step explanation:
The sum of odd numbers 1 .. n is ((n+1)/2)², a perfect square. Suzie is right about that. What Timmy has shown is that she is incorrect that the conjecture applies to <em>any</em> sum of consecutive odd numbers.
Timmy's sum of 5+7+9 is incorrect; it is 3·7 = 21. But, Timmy has the right idea. The sum of an arbitrary set of consecutive odd numbers will be the difference of two squares, but not necessarily a perfect square.
