<em> 2x = 18 - y</em> is a perfectly good equation just as it stands.
If you were considering representing the equation as a graph, then
you might want to rearrange it, into a form that immediately reveals
some characteristics of the graph. That would make your job easier.
You'd want to rearrange it into 'standard' form for graphing, with 'y' on
one side of the equation and everything else on the other side, like this:
<em> </em> <u>2x = 18 - y</u>
Add 'y' to each side: y + 2x = 18
Subtract 2x from each side: y = -2x + 18
In this form, the equation shows that when it's graphed, the slope
of the line will be -2, and the line will cross the y-axis at the point
where y=18 .
Answer: The answer is 27600 and 35152.
Step-by-step explanation: Given that the call letters of a radio station must have 4 letters and the first letter is one of K or W. We are to calculate the number of call letters that can be made if repetition is allowed and not allowed.
If repetition is not allowed, then we can choose the first letter in 2 ways, second letter in 25 ways, third letter in 24 ways and fourth letter in 23 ways. So, the total number of call letters will be
![N_{rna}=2\times 25\times 24\times 23=27600.](https://tex.z-dn.net/?f=N_%7Brna%7D%3D2%5Ctimes%2025%5Ctimes%2024%5Ctimes%2023%3D27600.)
If repetition is allowed, then we can choose the first letter in 2 ways, second letter in 26 ways, third letter in 26 ways and fourth letter in 26 ways. So, the total number of call letters will be
![N_{ra}=2\times 26^3=35152.](https://tex.z-dn.net/?f=N_%7Bra%7D%3D2%5Ctimes%2026%5E3%3D35152.)
Thus, the required answer is 27600 and 35152.
Answer: $22.8501
Step-by-step explanation:
Since their bill was $54.25 and they need to pay tax of 8% and leave a 17% tip, the total amount that will be paid will be:
= $54.25 + (8% × $54.25)
= $54.25 + (0.08 × $54.25)
= $54.25 + $4.34
= $58.59
We then add the 17% tip. This will be:
= $58.59 + (17% × $58.59)
= $58.59 + (0.17 × $58.59)
= $58.59 + $9.9603
= $68.5503
Since they want to split the bill evenly, we divide the total amount gotten by 3. This will be:
= $68.5503 / 3
= $22.8501
Each person will pay $22.8501
Answer:
-3
Step-by-step explanation:
-5 1/2 + 6 3/4 - 4 1/4
= 1 1/4 - 4 1/4
= -3
