Step-by-step explanation:
a,b) you can place all 17 in the middle and both circle will have 17 each. then remove 2 and place one each on separate sides. you can do this 8 times so that at the you'll end up with 1 in the middle and 8 each on separate sides.
the ways to do is then 9.
5x3-x+ 9x7 +4 +3x11
Answer:
115-X
Explanation:
First you multiply the 5x3
<u>15</u>-X+9x7+4+3x11
then the 9x7
15-X+<u>63</u>+4+3x11
then the 3x11
15-x+63+4+<u>33</u>
Now once you have completed the multiplication step you move on to <u>calculating the sum.</u> (Adding all the positive numbers)
<u>15</u>-x<u>+64+4+33</u>
115-x
10ax + 5bx - 8ay - 4by = 5x(2a + b) - 4y(2a + b) = (5x - 4y)(2a + b)
option d is the correct answer.
Answer:
The average score is 73
Step-by-step explanation:
Your average score is the sum of each of your tests scores multiplied by the weight of the test.
We have that:

You scored 60 on the final
The final is worth 50%
You scored 80 on the class project
The class project is 20%
Average score:
A = 90*0.3 + 60*0.5 + 80*0.2 = 73
