Answer:
25
Step-by-step explanation:
5/9 [12*6+(-42)-(-15)]
[tex]\frac{5}{9}[12*6+(-42)-(-15)][/tex]
We use order of operation PEMDAS
Parenthesis , Exponents , Multiply and Divide , Add and subtract
+ and - becomes minus, - and - becomes plus
[tex]\frac{5}{9}[12*6+(-42)-(-15)][/tex]
[tex]\frac{5}{9}[12*6-42+15][/tex]
simplify the second parenthesis
[tex]\frac{5}{9}[72-42+15][/tex]
[tex]\frac{5}{9}[30+15][/tex]
[tex]\frac{5}{9}[45][/tex]
Now 5(45)= 225, then divide by 9
[tex]\frac{225}{9}[/tex]
25
answer = 25
