the answer is 5.25 I believe. By following the order of operations
Parentheses
Exponent
Multiplication
Division
Addition
Subtraction
[tex] \frac{1}{4} (9 - 12) + \frac{1}{3} (9 + 9)[/tex]
[tex] \frac{1}{4} ( -3) + \frac{1}{3} (18)[/tex]
[tex] \frac{1}{4} (3) = - .75[/tex]
[tex] \frac{1}{3} (18) = 6[/tex]
[tex] 6 - .75 = 5.25[/tex]
