At gas-n-car wash, gasoline sells for $3.000/gallon and a carwash costs $12.00.luis wants to have his car washed and gas up his car but keeping the total cost under $50. a) write an inequality luis might use to determine how much gas he can get. b) determine if he can get 10 gallons of gas? 12 gallons? 13 gallons? justify. c) graph on a number line to represent the inequality. part a inequality:part b show your work

A) 12 + 3g < 50

B) He can get 10 or 12 gallons but not 13.

C) Graph with open circle on 12.67 on number line with the arrow pointing left or less than.

Step-by-step explanation:

To write the inequality, use the numbers given in the word problem. Luis will pay $12.00 for a car wash plus $3.00 per gallon and it must be less than $50.

12+3g < 50 where g is the number of gallons purchased.

Solve for g using inverse operations.

12-12+3g < 50-12

3g < 38

g < 12.67

This means Luis must buy less than 12.67 gallons to spend less than $50.

answer is d-29

step-by-step explanation:

since you didn't include the picture, i can give you the description so you know how to pick the correct answer. the third quartile of a data is always shown in a box plot. in the middle of your graph should be a box. the third quartile is the value that goes with the far right edge of the box.

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
