An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
The number of smokedetectors to be purchased.
= 12
Store A:
Cost of one smokedetector = $17
Cost of 12 smokedetectors.
= 12 x 17
= $204
Store B:
Cost of one smokedetector = $24
Cost of 12 smokedetectors.
= 12 x 24
= $288
Now,
The difference between the cost of 12 smokedetectors from store A to store B.
= $288 - $204
= $84
Thus,
The amountlessspend by buying in store Athan in store B is $84

Answer:
$84
Step-by-step explanation:
so for store A, you would do $17*12 smoke detectors, Which would give you $204. For store B you would do $24*12 smoke detectors. That is $288. Now all you do is 288-204=84. You would save $84 dollars going to store A
Answer:
the initial temperature is 22.5 atm
Step-by-step explanation:
The law describing pressure-temperature relationship is the Gay-Lussac's Law.
The Mathematical Form of which is:
=>
Where P1 = ? , P2 = 30 atm, T1 = 600 K and T2 = 800 K
=>
=> P1 = 0.0375 * 600
=> P1 = 22.5 atm
So, the initial temperature is 22.5 atm

Answer: There is 30% student plays either football or baseball.
Step-by-step explanation:
Since we have given that
Total number of students = 200
Percentage of students who play football = 22%
Number of students who play football n(F) is given by
Percentage of students who play baseball = 12%
Number of students who play baseball n(B) is given by
Number of students who play on both teams n(F∩B) = 8
According to rules, it becomes,
Probability that a student plays either football or baseball is given by
Hence, there is 30% student plays either football or baseball.
