The ratio of hamburgers to hot dogs is 6 to 5. Three times the number of hot dogs is 6 more than twice the number of hamburgers.

Kitty [74]

Answer:the number of hot dogs is 10

Step-by-step explanation:

Let x represent the number of hamburgers.

Let y represent the number of hot dogs.

The ratio of hamburgers to hot dogs is 6 to 5. This means that the ratio of x to y is 6/5

x/y = 6/5

5x = 6y

x = 6y/5

Three times the number of hot dogs is 6 more than twice the number of hamburgers. This means that

3y = 2x + 6 - - - - - - - - -1

Substituting x = 6y/5 into equation 1, it becomes

3y = 2(6y/5) + 6

3y = 12y/5 + 6

Multiplying both sides of the equation by 5, it becomes

15y = 12y + 30

15y - 12y = 30

3y = 30

y = 30/3 = 10

x = 6y/5 = 6×10/5

x = 60/5 = 12

mash [69]

The approximate probability that she checked a social website first, then a school-related website is 0.267.

First step is to calculate the Total number of websites

Total number of websites=Number of school websites+Number of social websites

Total number of websites=2+4

Total number of websites=6

Second step

Probability of checking the social website first

Probability of checking social website=Number of social websites/Total number of websites

Probability of checking social website= 4/6

Third step

Since one social website is checked which means that she is left with 3 social website and 2 school websites

Total number websites=2+3

Total number websites=5

Forth step

Probability of checking social website=Number of school websites/Total number websites

Probability of checking social website=2/5

Fifth step

Probability= 4/6 x 2/5 = 0.2666

Probability=0.267(Approximately)

Inconclusion the approximate probability that she checked a social website first, then a school-related website is 0.267.
