the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing.
Step-by-step explanation:
Rocky ate 42 cups of dog food. Since there are 7 days in a week, 21 cups were eaten per week (3x7). Since the question is asking for the amount in two weeks, you multiply 21x2 to get 42.
Answer:
(7-5)
Step-by-step explanation:
According to PEMDAS, parenthesis go first. But there are two sets of parenthesis so the one inside the other goes first.
Next would be [3+(2*2)]
Then, [3+4]
Then, -8/1
Then, -3(7)
So the question would be 4-8-21
Which gives you -25 as an answer.
I realize that you weren't asking for the whole thing but maybe there are follow up questions.

Step-by-step explanation:
7:30 plus 1 hour is 8:30. Quarter is 25 or 1/4. Then you add 8:30 plus 25 which gives you 8:55.
