Ok -7-7=-14 because your subtracting a negative with a negative and then it will be a negative then if you multiply a negative and a negative it will be a positive

If a theory is challenged, then that means that the theory may have a specific flaw, making it "not good"
Answer:
Step-by-step explanation:
if Jim eats r apples and Maria eats 3times as Jim then we can represent the number of times Maria eats as 3r
Together, the both eat 96 apples that is:
r + 3r = 96 apples - this is the equation for this situation.
Solving further
r + 3r = 96apples
4r = 96 apples (divide through the equation by 4)
4/4 r = 96/4 apples
Then
r = 24 apples
Which means that Jim eats 24 apples while Maria eats 3 * 24 apples = 72 apples.
They went there in 6.5 hours and came back in 5.8 hours
