Well the teacher would only get $15 but we don’t know how much the balls cost so you can’t make an expression
Answer:

Step-by-step explanation:
To find the coordinates of the point is 1/4 of the way from A (-6, -3) to B (6, 1), we are going to be using the midpoint formula, which states that:
The midpoint is at
. Where:


Then, the midpoint is at:
= 
Now, to find the coordinates of the point that is 1/4 of the way, we are going to calculate the midpoint between the point 'A' and the midpoint previously caculated, as follows:


⇒
= 
Therefore, the point is 1/4 of the way from A to B is: 
Answer:
6
Step-by-step explanation:
you will multiply 40 times .85 since the percent you move the period two times to the left you will get an answer of 34.
you will then subtract 34 out of the 40 and you will get the answer 6.
18/20=K/110
20K= 110*18
20K= 1980
K= 99
The mistake is n third line - adding 3w
96 + 2w =2(80 - 3w)
96 + 2w = 160 - 6w
+ 6w + 6w
96 + 8w = 160
- 96 -96
8w = 64
w = 8 weeks answer
