    1) 5<10x

    5/10>x

    1/2>x

    2) 4 + (8.4) =9x

    36=9x

    36/9=x

    4=x

    3)5(5.1).(8+1)=5.5.9

    =225

    4)I'm from Argentina and I don't know if 9 to the power of 5 is done by multiplying 9 5times. If it is like this the anwer would be: 59049.

    5)-3(15-30)+(-58.2)=-3.-15 + (-116)

    =45-116

    =-71

    1. X is greater than or equal to 1. 10 is already bigger than 5. So long x is not smaller than 1 (0, -1, -14, etc.).

    2. I can't tell what sign is between the 8 and the 4. If it is a multiplying sign, then the answer is x=4. 8 times 4 is 32, plus 4 is 36. 36 divided by nine is 4.

    3. PEMDAS. "Parenthesis, Exponents, Multiplication, Division, Addition and Subtraction.

    The answer is 225.

    4. The anwer is 59,049.

    5.The answer is -71.
