At a concession stand, seven hot dogs and two hamburgers cost $16.25; two hot dogs and seven hamburgers cost $17.50. Find the cost of one hot dog and the cost of one hamburger.
Answers
The cost of 1 hot dog is $1.75 and the cost of 1 hamburger is $2.
Let x be the cost of one hot dog and y be the value of one hamburger. we will set up a system of linear equations to solve for x and y:
From the first statement, we recognize that:
7x + 2y = 16.25 ----(1)
From the second statement, we know that:
2x + 7y = 17.50 ----(2)
We will use both substitution or elimination method to solve this system of equations. let's use elimination method right here. we are able to multiply equation (1) through 7 and equation (2) by 2 to eliminate y:
49x + 14y = 113.75 ----(3)
4x + 14y = 35 ----(4)
Subtracting equation (4) from equation (3), we get:
45x = 78.75
Dividing each sides by using 45, we get:
x = 1.75
Substituting x = 1.75 into equation (1), we can solve for y:
7(1.75) + 2y = 16.25
12.25 + 2y = 16.25
2y = 4
y = 2
Consequently, the cost of 1 hot dog is $1.75 and the cost of 1 hamburger is $2.

Answer:
A. 25°C
Step-by-step explanation:
C=5/9(77-32)
C=5/9(45)
C=25°C
Convert 77 °F to °C
To convert from Celsius to Fahrenheit. We apply the following formula:
We substitute the number 77 where the Fahrenheit degrees are, and we are left with the following form.
So 77 Fahrenheit, on the Celsius scale is 25.So the correct alternative is option "A".
