Answer: She Is Not Correct The Answer Is 24

Step-by-step explanation: The answer is 24. This is because when you have order of operations, you always do parentheses first. (27-9) equals 18. Then multiply it by 3 so do 20 times 3 and then subtract 6 and you get 54. Then divide 54 by 9 and you get 6. 6+18 does not equal 42 so it would be the third one.

Answer:

the answer is C.

Step-by-step explanation:

using pemdas you start with parenthesis,

(27-9)*3÷9+18=42

18*3÷9+18=42 .         use rules of multiplication and division

54÷9+18=42             divide again

6+18=42                  add

24=42

this is false because the numbers don't match up on the left and right side, so 24 is the real answer.
