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.
Hey there! :)
When teachers ask you for the standard form in math, they are asking you to find the simplest form an equation with variables can be in.
Ax + By = C
Example : put y=2x -3 into standard form.
Subtract 2x from both sides.
-2x + y = -3 —> standard form.
Hope this helped! :)
Answer:
u r correct
look at the picture I sent
Take away 0.20 of the amount.
Rewriting literal equations is useful when solving problems by helping us get more organized with the problem. If the problem is organized, than it is much easier to solve. (I hope this answered your question)
