Answer:
D.) x = 3
Step-by-step explanation:
4 + 3x = 2(3x - 7) + 9
4 + 3x = 6x - 14 + 9
3x - 6x = 9 - 14 - 4
-3x = -9
x = -(-9)/3
x = 9/3
x =3
possible way Harry might buy the hamburgers and hot dogs?
69 hamburgers and 28 hot dogs
64 hamburgers and 35 hot dogs
66 hamburgers and 33 hot dogs
78 hamburgers and 20 hot dogs
The possible way Harry buy the hamburgers and hot dogs is 66 hamburger and 32 hot dogs
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
