Mathematics

zaharov [31]3 years ago
5 0

Answer:

Statements 2 and 3.

Step-by-step explanation:

The first statement is impossible since you cannot have half a person. The last statement is also incorrect, because it would imply that the total number of students in the class is -29. The second statement is correct, if you assume that x and y represent either the number of male or female students. The third statement is possible, and the numbers add up to 29. Finally, the fourth statement is impossible because it would imply that the class had negative male students. Hope this helps!

A company rents out 15 food booths and 20 game booths at the country fair. The fee for a food booth is $100 plus $5 per day. The
Gennadij [26K]

Answer:

So the required expression is $(150 + 12d)

Step-by-step explanation:

Total Food booths rented = 15

Total game booths rented = 20

Fixed one day food booth Price = $100

Per day price of food booth = $5

Fixed one day game booth Price = $50

Per day price of game booth = $7

Total No of days = d

To write an expression the company paid for  both in dollars

As we have got the no of days

So Company paid Money for d days for food booth = Total days * price per day

                                                                              = d * $ 5

                                                                              =$ 5 d


So Company paid Money for d days for game booth = Total days * price per day

                                                                              = d * $ 7

                                                                              =$ 7 d

Total Paid for food booth = Fixed price + D days Price

                                          = $ 100 + $ 5d

Total Paid for game booth = Fixed price + D days Price

                                          = $ 50 + $ 7d

Total Company Paid = Total Paid for food booth + Total Paid for game booth

putting in the values gives us                  

Total Company Paid = $(100 + 5d) + $(50 +7d)

Adding the similar terms gives

Total Company Paid = $(100 + 50) + $(5d +7d)

Total Company Paid = $(150 + 12d)

So the required expression is $(150 + 12d)

Louis bought a burger and soda for $8. Kate purchased a slice of pizza and soda for $9. David purchased a burger, a slice of piz
padilas [110]

Answer:

cost of a burger= $4.5

Cost of soda = $3.5

Cost of a slice of pizza = $5.5

Step-by-step explanation:

Let x = the cost of a burger.

Let y = the cost of a soda.

Let z = the cost of a slice of pizza.

Louis bought a burger and soda for $8. This means

x + y = 8 - - - - - - - -1

Kate purchased a slice of pizza and soda for $9. This means

z + y = 9 - - - - - - - - - 2

David purchased a burger, a slice of pizza, and a soda for $13.50. This means

x + y + z = $13.50 - - - - - - - 3

Substituting x = 8-y and z = 9-y in equation 3, it becomes

8-y + y + 9-y = 13.50

-y -y + y = 13.50 -8-9

-y = -3.5

y = $3.5

Put y = 3.5 in equation 1

x + 3.5 = 8

x = 8 - 3.5 = $4.5

Put x = 4.5 and y = 3.5 in equation 3.

4.5 + 3.5 + z = 13.5

8 + z = 13.5

z = 13.5 - 8 = $5.5
