The possible way Harry buy the hamburgers and hot dogs is 66 hamburger and 32 hot dogs
What is Linear equation?
An equation between two variables that gives a straight line when plotted on a graph.
Given,
Price of hamburger = $0.50
Price of hot dog = $0.25
Consider,
Number of hamburger is x and number of hot dog is y
Then,
x + y = 98
y = 98 - x
0.50x +0.25y = 41
Substitute the value of y in this equation
0.50x + 0.25(98 - x) =41
0.50x +24.5 -0.25x = 41
0.25x + 24.5 = 41
0.25x =16.5
x =
x + y = 98
Substitute the value of x
66 + y =98
y = 98 - 66
y = 32
Hence, the possible way Harry buy the hamburgers and hot dogs is 66 hamburger and 32 hot dogs

Answer:
B: 64 hamburgers and 35 hot dogs
Step-by-step explanation:
64 x . 5 = 32 and 35 x .25 = 8.75
Add 32 + 8.75 = 40.75

-5x+7y=11
Answers
-5x+7y=11
Here, we use substitution to solve for both variables.
Solve for y first
-5x + 3y = 19
+5x +5x
3y = 19 + 5x
y = 19/5 + 5/3x
Now plug that into the other equation. -5x+7(19/5 + 5/3x) =11
-5x + 26.6 + 35/3x = 11
-5x + 35/3x = 20/3x
20/3x + 26.6 = 11
-26.6 -26.6
11 - 26.6 = -15.6
20/3x = -15.6
x = -119.6
Ahhh, now time to solve for y
-5x+3y=19
-5(-119.6) + 3y = 19
598 + 3y = 19
-598 -598
19 - 598 = -579
3y = -579
y = - 193
WE ARE DONE!!!
Answer: y = -193 and x = -119.6

Step by step explanation:
To get the answer you must expand the brackets (multiply the number or numbers outside the brackets with the ones within to remove them)
To do this you must first in 2(8+6) multiply 2 times 8 which is 16
Then you would multiply 2 times 6 which is 12
As the operation is a + that would mean the answer is 16+12
Hope this helps!
