Alicia is solving the equation 2.3 x minus 1.6 = 8.8 minus 2.9 x. Which equations represent possible ways to begin solving for x? Check all that apply.
2.3 x minus 10.4 = negative 2.9 x
5.2 x minus 1.6 = 8.8
Negative 6.5 x minus 1.6 = negative 2.9 x
2.3 x + 1.3 = 8.8
2.3 x = 10.4 minus 2.9 x
2.3 x - 1.6 = 8.8 - 2.9 x
+ 1.6 +1.6
2.3 x = 10.4 - 2.9 x
2.3 x - 1.6 = 8.8 - 2.9 x
-8.8 - 8.8
2.3 x - 10.4 = 2.9 x
2.3 x - 1.6 = 8.8 - 2.9 x
+2.9 x + 2.9 x
5.2 x -1.6 = 8.8

Answer:
Question 1: 367.5 ft squared
Question 2: 21.6 miles
Step-by-step explanation:
Answer:
11. 367.5 sqft 12. 21.6 sqmiles
Step-by-step explanation:
Well for 11. if each inch is 3.5 feet then you would wan t to multiply 5 and 6 by 3.5. You get 17.5 and 21. To find area, you'll have multiply the height and width which is 17.5 and 21. Once you do that you end up with 367.5ft squared.
For 12. each inch is 4.8 mines and there are 4.5 inches. So you want to do 4.5 times 4.8 which gives you 21.6 square miles. I hope you do well.
A student wants to find the answer to the question “What is the most popular restaurant in Bedford?” He asks 20 randomly selected customers at one local restaurant. Which best describes the accuracy of the results of the survey? The survey results will be accurate since the sample was chosen randomly. The survey results will be inaccurate since the entire population should have been surveyed. The survey results will be inaccurate since the entire sample of the population was eating at the same restaurant. The survey results will be accurate since the sample represents the population and the population is the target of the survey.
Answer:
The survey results will be inaccurate since the entire sample of the population was eating at the same restaurant.
Step-by-step explanation:
When doing a survey you must make sure it is unbiased by asking a variety of people for example if you are wondering what is the favorite class at school you have to ask a certain amount of people from each class because if you ask only people from P.E the answer more than likely will be P.E or if u ask 3 people from Art and 17 from P.E your answer will properly be P.E. Make sense?
Answer:
The correct answer is C. The survey results will be inaccurate since the entire sample of the population was eating at the same restaurant.

Emanuel and three of his friends go out to dinner. Their total bill at the end of the meal is $255.38. Since their food was not cooked correctly, they receive a 20% discount. If they pay an 11% tax on their meal, how much did each person pay for dinner if they decide to split the check equally among them?
Answer:
Step-by-step explanation:
Multiply 255.38 times 0.20 (20%). You get 51.076. Subtract 51.076 from 255.38. You get 204.304. Multiply this by 0.11 (11%). You get 22.47344. Add this to 204.304. You end with 226.77744. Divide this by 4. You get 56.69436 or $56.69 a piece.
