It's A and C, I've taken a test that has this question and it was correct when I answered this, so A and C is your answer.
Idk if you are talking about independent and dependent variables but if you are then the independent variable is the variable that is changed or controlled and the dependent variable is the variable being tested and measured in a scientific experiment. Hope this helps!!!❤️
Since in this equation we are dividing 17/2 by 1/4, we can think of this as multiplying 17/2 with 4/1 (or 4).
17 4
---- X ----- = 34
2 1
Our final answer is 34 days.
