For the 4 night at the hotel, the answer is 290 since you insert 4 in where the x should be 150+35(4). For the second question, the answer is 8 since you subtract the money you have (430) by the parking cost (150). This lead to 280 and you divide it by the amount you need to spent on hotel charge per night (35) and you get 8. That means that you can spend 8 night at the hotel.
Answer: Equivalent expressions
14⋅x or 6+8x
The one-way flight is represented as 150x-100miles. If we have a round trip distance to be computed, then we need to multiply it twice such as the solution is shown below:
(150x-100)*2
300x-200
Therefore, the answer is letter "C" which is 300x-200.
Answer:
25x^2+40x+16
Step-by-step explanation:
We have to distribute each term to the other terms.
Let's take the first 5x and multiply it by 5x and 4 in the second set of parentheses.
5x*5x+5x*4
25x^2+20x
Now we have to multiply the first 4 by, again, 5x and 4
4*5x+4*4
20x+16
Now we combine the two bolded expressions.
25x^2+20x+20x+16
Now we combine like terms
25x^2+40x+16
Hope this helps!
Answer:
A. Based on the procedure by which this figure was generated, it is likely that the population proportion is between 44.5% and 51.5%.
Step-by-step explanation:
Confidence interval:
We build a confidence interval from a sample proportion, to get an estimate of where the population proportion should likely be.
48% of voters surveyed favored the reelection of Congressman Porkbarrel, with a margin of error of 3.5%.
48 - 3.5 = 44.5%.
48 + 3.5 = 51.5%.
Following the concept of a confidence interval, the population proportion is likely to be between 44.5% and 51.5%, and thus, the correct answer is given by option A.
