Answer:
The correct anser is option
B. 2x + 2 = 18
Step-by-step explanation:
Let the number of hot dogs eaten by the runner up be represented by x
If Dave ate 2 more than twice x, this means that the number eaten by him = 2x + 2
Since the total number of hot dogs eaten by Dave is 18
Therefore, the equation will be
2x + 2 = 18
So the number of hot dogs eaten by the runner-up is determined by solving for x
2x= 18-2
2× = 16
x = 16/2
x = 8
The runner up are 8
While Dave are
2×8 + 2 = 18.
Answer:
When solved for x, the runner-up ate 2x + 2 = 18
Step-by-step explanation:
Dave won by eating 18 hot dogs
He ate two more than twice the amount of the runner-up.
Suppose the runner-up ate x-hot dogs.
That means Dave ate two more than twice of x. This can be written as
Twice of x is 2x
And two more than twice of x is 2x + 2.
So, Dave ate (2x + 2) hot dogs.
Since we already know that Dave ate 18, we can say
2x + 2 = 18
2x = 16
x = 8
