Answer:

Megan needs a 95 to get an average of 90.

Step-by-step explanation:

Add up the test scores Megan has earlier, you would get 355 as a result of all scores added.  In order to get an average of 90%, you would need to accumulate 450 points which she will need to take her final exam on it.  Subtract 355 from 450 to get a score of 95% in which she will need that score to average it to 90%.

Which of the following is the best estimate for 31% of 9? *GIVING 99 Points!*
Marina CMI [18]
Hello! So, when you know your fractions and percents, you know that about 33% equals 1/3. 31 is close to 33, so the best estimate for 31% of 9 is 3. When you solve it on a calculator, 9 * 31% (0.31) is 2.79, which rounds off to 3 when rounded to the nearest whole number. The answer is B: 3.

Wittaler [7]

Answer:

-4 5/12

Step-by-step explanation:

-23/3 + (-11/2) + 35/4

<em>Find a common denominator (12).</em>

-92/12 + (-66/12) + 105/12

<em>Reform the equation to have this as a single fraction.</em>

(-92 + (-66) + 105)/12

<em>Subtract 66 from -92 to get -158.</em>

(-158 + 105)/12

<em>Add 105 to -158 to get -53.</em>

-53/12

<em>Convert into a mixed number by dividing by 12.</em>

-4 5/12 (Choice A) is your answer.
