Hello!
First we have to define a variable.
Let x stand for the price of a granola bar
Then we have to make our equation
1250x + 25 = 800
This is the equation because the price for all the granola bars and delivery was $800
Now we solve it
Subtract 25 from both sides
1250x = 775
divide 1250 from both sides
x = 0.62
The cost for a granola bar is $0.62 or 62 cents
Hope this helps!
You use explicit funtion to find a particular number in the list without needing to write all the list down.
For example, the first range of number has a constant difference of 5. Its explicit funtion would be: x(n)=3+(n-1)*5 (with x is the number you need to find, n is the number's position in the range)
Basically, a explicit funtion in that problem has the form:
x(n)=f+(n-1)*d
with:
x= the number needed to find
n= the number's position
f = the first number in the range
d = the distance
Good luck!

Answer:
The required biconditional statement is: If Smith is guilty, if and only if Jones is innocent.
Step-by-step explanation:
From the provided statement.
The statement is: If Smith is guilty, then Jones is innocent.
The converse is: If Jones is innocent, then Smith is guilty.
The combination of a conditional statement and its converse is called biconditional statement.
The biconditional statement contains if and only if phrase between two part of the statement.
Which means the statement and converse both are true.
Therefore, the required biconditional statement is: If Smith is guilty, if and only if Jones is innocent.
Factor 4 out of 4x+20.
