- <em>Two negative consecutive integers have a sum of -45. What are the integers?
</em>
<em />-22 + -23
- <em>The sum of two consecutive integers 75. What are the two integers?</em>
37 + 38 = 75
- <em>What <u>three</u> consecutive odd integers have a sum of 81?
</em>
<em />25 + 27 + 29 = 81

Answer:
A) N = 20 ways
a 3-person subcommittee can be selected from a committee of 6 people in 20 ways.
B)N = 120 ways
The president, vice president and secretary can be chosen from a committee of 6 people in 120 ways.
Step-by-step explanation:
A) the number of ways a 3-person subcommittee be selected from a committee of 6 people N;
Since there is no given order for the selection, this means that the order of selection is irrelevant. Therefore, this is a combination problem where order is not considered.
N = nCr
N = 6C3
N = 6!/3!(6-3)! = 6!/3!3!
N = 720/(6×6)
N = 20 ways
a 3-person subcommittee can be selected from a committee of 6 people in 20 ways.
B) the number of ways a president, vice president and secretary can be chosen from a committee of 6 people N;
In this case, there is a given order of selection for the 3 posts. This is a permutation.
N = nPr
N = 6P3
N = 6!/(6-3)!
N = 6!/3!
N = 120 ways
The president, vice president and secretary can be chosen from a committee of 6 people in 120 ways.
Answer:
Therefore the total cost of 
pound of almonds and pound of cashews is
[Where y is in $]
Step-by-step explanation:
[The unit of price is not given, I assume the unit of cost as $]
Given expression is 14.42 d + 12.24 c .
Where the amount of almond is denoted by d pounds.
and the amount of cashews is denoted by c pounds.
The cost price of d pound of almond is $14.42.
The cost price of 1 pound of almond is 
Then the cost of pound of almond is 
Again from the given expression we get that,
The cost price of c pound of cashews is $12.24
The cost price of 1 pound of cashews is 
Then the cost of pound of cashews is 
Therefore the total cost of pound of almonds and pound of cashews is
y = 
[Where y is in$]
