  2. Answer : 702

    Explanation: Just multiply 78 by 9 and it gave you 702. The parentheses doesn’t mean anything in this :)!

  3. x=9

    Step-by-step explanation:

    -9x+1=-80

    To eliminate the one, you subtract one from both sides.

    That gives you:

    -9x=-81

    Then you divide both sides by negative nine to get x by itself.

    x=9

  4. 7. Approximately 402.7 inches or 2pi times 64

    8. 31.83 To solve this you know 2pi r is an equation for the radius. 2πr=200 and r=200/2π=100/π= 31.83.

    9. The one with pi in the equation because 3.14 is only a piece of pi but the symbol represents the whole number which goes on forever.

    Step-by-step explanation:

  5. 3 1/3 - 1 5/9

    get a common denominator 9

    3 1/3*3/3 - 1 5/9

    3 3/9 - 1 5/9

    borrow from the 3

    2 9/9+3/9 - 1 5/9

    2 12/9 - 1 5/9

    1 7/9

  6.  16/9

    Step-by-step explanation:

    Simplify the following:

    3 + 1/3 - (1 + 5/9)

    Put 1 + 5/9 over the common denominator 9. 1 + 5/9 = 9/9 + 5/9:

    3 + 1/3 - 9/9 + 5/9

    9/9 + 5/9 = (9 + 5)/9:

    3 + 1/3 - (9 + 5)/9

    9 + 5 = 14:

    3 + 1/3 - 14/9

    Put 3 + 1/3 - 14/9 over the common denominator 9. 3 + 1/3 - 14/9 = (9×3)/9 + 3/9 - 14/9:

    (9×3)/9 + 3/9 - 14/9

    9×3 = 27:

    27/9 + 3/9 - 14/9

    27/9 + 3/9 - 14/9 = (27 + 3 - 14)/9:

    (27 + 3 - 14)/9
