Answer:
Jesse = 18yrs
Adam = 9yrs
Denise = 6yrs
Step-by-step explanation:
Denise = x
Adam = x+3
Jesse = 2(x+3)
x+x+3+2x+6 = 33
4x+9 = 33
4x = 33-9
4x = 24
x = 6yrs
Substitute :
Denise = 6
Adam = 6+3 = 9
Jesse = 2(6+3) = 2(9) = 18
You can have a number line showing eigths and place the 2 fractions on the number line in the correct place.

Convenience sampling
Step-by-step explanation:

Here, the reporter failed to eliminate any sort of possible bias which may be present, as all was sacrificed for the sake of convenience or ease.
