Answer:
1. By substitution property of inequality
5(9.5)+4.565
2. By using multiplication in equality then we get
47.5+4.5x65
3. The five friends will have 3 snacks to split.
Step-by-step explanation:
Given
Five friends have total money= $65
Cost of each movie ticket= $9.50
Cost of each snack item= $4.50
Let ,five friends have total snacks = x
Total movie tickets=5
Because total number of friends=5
The inequality expressionis given by
I Step:
Reason: By using substitution property of inequality
65-47.5[/tex]
( by subtarction 47.5 from both sides)
( by dividing 4.5 on both sides )
Because they can buy maximum 3 snacks .
Beacause the number of snacks is natural number so we can't take in rational numbers.
<h3>Hence, the five friends will have 3 snacks to split.</h3>Answer:
$95.77
Step-by-step explanation:
We are told that Tim wants to purchase a watch for $98.99.
He has a coupon that will discount the watch by 10%. So price of watch after using coupon will be,
Now let us find the price of watch after sales tax of 7.5%.
Therefore, Tim will pay $95.77 at the register.
Answer:

If <u>all prime numbers are odd,</u> then <u>2 is odd</u>.
2 is not odd.
Therefore, it is not the case that all prime numbers are odd.
Step-by-step explanation:
Considering part A
The first sentence is
If all computer programs contain errors, then this program contains an error.
The second sentence is
This program does not contain an error.
The third sentence is
Therefore, it is not the case that all computer programs contain errors.
Now we will use a and b as the letter to denote the component sentences and and
when the component sentences is not the case
So a = If all computer programs contain errors
and
b = this program contains an error.
Generally then is represented as
Hence the first sentence is denoted as
The second sentence is represented as
The third sentence is represented as
So part a can be represented as
Considering part B
Here the objective is to fill in the blank spaces so that the logic of the sentence in part b is as that in part a
Now comparing the second statement a and b
"This program does not contain an error" = "2 is not odd" =
Hence "this program contains an error." = "2 is odd" = b
Now comparing the third statement a and b
Therefore, it is not the case that all computer programs contain errors.
=
Therefore, it is not the case that all prime numbers are odd
=
Hence
If all computer programs contain errors, = if all prime numbers are odd.= a
