Which part do you need help on?
We find the average by adding up all the students and dividing them by the number of classes she has. 19 + 13 + 19 + 9 + 14 + 15 is 89, and that divided by 6 is approximately 14.8, rounded to the nearest tenth.

Hope this helps!
The middle number is 0 and the last is -81Factoring means we want something like(b+_)(b+_)We need two numbers that add together to get and Multiply to get -81which are 9 and -9:<span><span>9+-9 = 0 and </span><span>9*-9 = -81</span></span>
Fill in the blanks in
(b+_)(b+_)
with 9 and -9 to get...<span><span>(<span>b+9</span>)</span><span>(<span>b−9</span>)</span></span>
The answer is : (b+9)(b−9)

Answer:
8x - 6 = x + 9 : Given
7x - 6 = 9 :Subtraction property of equality
7x = 15 : Addition property of equality
x = 15/7 : Division property of equality
x = 2.143
Step-by-step explanation:
Match the properties with the steps to solving the following equation.
(8x - 6) = x + 9
8x - 6 = x + 9 : Given
8x - x - 6 = x + 9 - x
7x - 6 = 9 :Subtraction property of equality
7x - 6 + 6 = 9 + 6
7x = 15 : Addition property of equality
7x/ 7 = 15/7
x = 15/7 : Division property of equality
x = 2.143
The “math sentence”: To find the answer, I need to divide the six chocolate bars by 3/4.
To model the situation, you need to draw 6 squares divided into quarters. Color in 3 of the quarters in each square.
Finally, write this for the solution sentence:
By giving 3/4 of a chocolate bar to each of her friends, Mrs. Lopes will be able to share her 6 chocolate bars with 8 different friends.
Hope you get that A+!
