Use PEMDAS for the order of operations:
Parentheses
Exponents
Multiplication/Division
Addition/Subtraction
Plug your p and q values into the equation:
[tex]15 + 3(10) \div -5[/tex]
3(10) includes parentheses, so operate on that first:
[tex]3 * 10 = 30[/tex]
[tex]15 + 30 \div -5[/tex]
30 / -5 is division, so operate on that next:
[tex]30 \div -5 = -6[/tex]
[tex]15 + -6[/tex]
Finally, we have addition, so operate on that last:
[tex]15 + -6 = 9[/tex]
The answer is A. 9.
