Explain It Adam made 19 paper cranes Monday and 8 more Tuesday. He gave 9 friends an equal number of cranes. How many cranes did each friend received? Explain how you found your answer.

Answers

Answer: Each friend received 3 paper cranes.

Step-by-step explanation:

Given : Number of paper cranes made by Adam on Monday = 19

Number of paper cranes made by Adam on Tuesday = 8

Total number of paper cranes made by Adam = (Number of paper cranes made on Monday) + (Number of paper cranes made on Tuesday )

= 19+8

= 27

Now , all paper cranes are equally divided into 9 friends , the number of paper cranes received by each friend = (Total number of paper cranes ) ÷ (9)

= (27)÷ (9)

= 3

Hence, each friend received 3 paper cranes.
he made  19 paper cranes on Monday & 8 more on tuesday
total cranes made =    19 + 8  = 27
number of cranes he give to each of his 9 friends =      27/9  = 3 cranes

4x + 8z = 2. Solve for z

Answers

Step-by-step explanation:

4x + 8z = 2     Subtract 4x from both sides

8z = 2 - 4x      Now, divide both sides by 8

z = (2-4x) / 8                     or          (1-2x) / 4

Tracy goes on a 3 day and night school band trip. There is no cost for travel and each band member only pays half the cost of the hotel room. However, each person is responsible for the cost of their own meals. His portion of the hotel bill is $49 per night and Tracy leaves a 10% tip for the maid service. Before tax, Tracy spends $32 per day on eating out plus 15% of this amount in tips. If Tracy spends a total of $280.74 on the band trip, what percent tax was Tracy charged on his food?

Answers

The total amount she spent is equal to the sum of the amount for food and hotel accommodation. Letting x be the percent tax that Tracy was charged for his food, the equation that best represent the given is,
                       280.74 / 3 = 49 + (0.10)(49) + 32 + (0.15)(32) + (x)(32)
The value of x from the equation is 0.09. Thus, Tracy is charged 9% tax on his food. 

Answer:

9%
