Step-by-step explanation:
During a football game, a concession stand sold a family 2 hamburgers and 2 hotdogs for a total of $13. It sold another family 2 hamburgers and 5 hotdogs for a total of $16. What are the prices of a hamburger and a hotdog?
Answer:
The price of each hamburger is $3
The price of each hot dogs is $2 .
Step-by-step explanation:
Given as :
The total price of 3 hamburger and 2 hot dogs = $13
The total price of 2 hamburger and 5 hot dogs = $16
Let The price of each hamburger = $x
Let The price of each hot dogs = $y
Now, According to question
3 x + 2 y = 13 .........A
2 x + 5 y = 16 .......B
Now, Solving to eq A and B
3 × (2 x + 5 y ) - 2 × (3 x + 2 y ) = 3 × 16 - 2 × 13
Or, (6 x + 15 y) - (6 x + 4 y) = 48 - 26
Or, (6 x - 6 x) + (15 y - 4 y) = 22
Or, 0 + 11 y = 22
∴ y =
i.e y = $2
so, The price of each hot dogs = y = $2
Now, Put the value of y into eq B
i.e 2 x + 5 y = 16
or, 2 x + 5 × 2 = 16
or, 2 x = 16 - 10
or, 2 x = 6
∴ x =
i.e x = $3
So, The price of each hamburger = x = $3
Hence, The price of each hamburger is $3 and The price of each hot dogs is $2 . Answer
Answer:
the hamburgers are 6.50 and hot dogs are 3 dollars

Answer:1,170 i think what are u exactly trying
to find
Step-by-step explanation:
Answer:
108
Step-by-step explanation:
So we can break this figure into 2 shapes. A rectangle and a right triangle.
Once we do that, we can solve the area for each shape.
Rectangle: 6 x 3 = 18
For the triangle, we'll need to find the sum of 6 + 6, which would be 12 to find the missing height for the triangle. Then we can find the area.
Triangle: (12 x 15)/2 = 90
We can then add our two answers up to get our final answer.
18 + 90 = 108

Step-by-step explanation:
1/2 x 4/7
All you have to do, is multiply from across
1*4/ 2*7
4/14 = 2/7 when it's simplified ( i divided them by 2, the numerator and denominator)
__________________________________________________________
2/3 x 1/6
same as usual, multiply from across
2*1/3*6
2/18 = 1/9 when it's simplified ( i divided them by 2, both the numerator and denominator)
__________________________________________________________
1/4 ÷ 3/8
KCF = Keep Change flip
Keep the 1/4
Change the division side to multiplication
Flip the 3/8 to it's reciprocal ( 8/3)
1/4 × 8/3
Now multiply from across
1*8/4*3
8/12 = 2/3 when simplified ( divided them by 4, the numerator and denominator)
Hope this helped!
