Answer:

7 sec(y) cos(y) = 7

8-5/6÷7/8 please help, not sure if my answer is correct. Just need the answer and possibly the work
xxMikexx [17]

For this case we must solve the following expression:

8- \frac {5} {6} ÷ \frac {7} {8}

According to the PEMDAS algebraic order method, we have the following order:

P: Parenthesis

E: Exponents

MD: Multiplication and division

AS: Addition and subtraction

So, we have:

8- \frac {\frac {5} {6}} {\frac {7} {8}} =\\8- \frac {5 * 8} {6 * 7} =\\8- \frac {40} {42} =\\8- \frac {20} {21} =

\frac {8 * 21-20} {21} =\\\frac {168-20} {21} =\\\frac {148} {21} =\\7 \frac {1} {21}

Answer:

7 \frac {1} {21}
