  1. D) Emerson must earn at least a 94 on his final test to earn an “A” in his class

    Step-by-step explanation:

    We calculate this using mean in this format:

    Test Scores / # of Test ≥ 90 (which is an A)

    Substitute:

    (92 + 86 + 88)+ x / 4 ≥ 90

    Add:

    266 + x / 4 ≥ 90

    Get Rid of the Denominator:

    (4) 266 + x / 4 ≥ 90 (4)

    Multiply:

    266 + x ≥ 360

    Isolate x (Subtract 266 From Both Sides):

    x ≥ 94

    This means that x (His final test score) has to be greater than (above) or equal to 94. A term for greater than or equal to is “at least.” Hope this helps 🙂

  2. answer: 16

    step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

    hope this ^_^
