Answer:
Step-by-step explanation:
In the triangle we have the following trigonometric equations:
and also:
The reaction of an acid with a base is called a neutralization reaction.
Answer:
- 20 - (3 × 23 - 5) =
- 20 - (69 - 5) =
- 20 - 64 =
- - 44

So to find average, we add up the values, and divide it by how many values there are in total.
27 + 12 + 31 + 19 + 23 + 11 + 17 = 140.
There are 7 numbers. Which means we divide 140 by 7.
140 / 7 = 20 is the average.
Also, if you notice, most of the numbers "kind of" circulate around 20.
Let x represent number of boxes of cookies and y represent popcorn bags.
We have been given that Ava sold 10 boxes of cookies and 8 bags of popcorn and raised $102. We can represent this information in an equation as:
We are also told that Greg sold 4 boxes of cookies and 12 bags of popcorn and raised $98. We can represent this information in an equation as:
Now we will use substitution method to solve our system of equations.
Form equation (1), we will get:
Upon substituting this value in equation (2), we will get:
Therefore, each bag of popcorn costs $6.5.
