Sammy goes to mcdonalds for lunch. he is on a diet that requires that he consume no more than 150 grams of carbohydrates for lunch. sammy enjoys mcdonald’s filet o fish sandwiches and french fries. each filet o fish has 45 grams of carbohydrates and each small order of french fries has 40 grams of carbohydrates. write a linear inequality that describes sammys options for eating at mcdonald’s

45x + 40x = 150

Step-by-step explanation:

the total we are trying to reach or get relatively close to without exceeding is 150 because that is the total amount of carbs he can eat. We do not know how many sandwiches or orders or fries he ate but he do know how many carbs are in each of them. if we assume he only ate one of each we can add up his total carbs 45+ 40 = 85 which is less than 150 but since we don't know if he really only ate one we can but and "x" value to fill in once we are given the missing information. the "x" value can stand for any number, in this case it's the total number of burgers and the total number of fries that Sammy ate.

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
