5

The only thing different is the bracket. Please HELP me i am stuck. Oh and Please explain your answer!!!

Answer 1

B. You must use brackets or parenthesis around the numerator since the numerator contains more than 1 term or operation.

If you choose A, then only 3 is divided by 5. In B, the entire expression in the numerator is divided by 5. So, you must choose B.

Answer 2

B, the whole numerator is divided by 5. In A, only the 3 is div. by 5.

Answer 3

B. The bracket is another way of grouping things together, so it would be like taking bracketing the whole top. I would recommend seeing which one is right by using a calculator next time you get stuck though.

Answer 4

Answer is B. Its because the 5 is over the whole thing and not just 3 in A. Basically it would look like this in another way: [(9-7)^2]/5 + 3/5

Answer 5

where is the variable x or y in your equation
