When multiplying (or dividing) both sides of an inequality by a negative number, the inequality symbol must be reversed/flipped, regardless of how many steps taken when solving the inequality.
If you were to multiply (or divide) by a positive number, then you would not have to reverse/flip the inequality symbol.
The question in the image is incomplete, so I cannot provide a true/false answer, but this information should be what you need to easily choose an answer.
Let me know if you need any clarifications and happy studying~

Move x terms to one side, then solve
Answer:
Vitamin C levels
Step-by-step explanation:
In order to identify which is the dependent variable in a experiment, it is useful think which is the variable being tested in the experiment. Whereas for the independent variable you need to check which is the variable that is usually controlled to test its effects on the dependent variable.
In this case you are measuring vitamina C levels (dependent variable) which you expect that depends on the fruit which you are testing (variable independent).
Note that the environmental conditions are factors which can affect also your dependent variable but you are not controlling that. They could be independent variables if you manipulate them.
Im pretty sure
a = 65
b= 80
