Answer:

Step-by-step explanation:
1. The initial equation given to us is
. Rearranging the equation to isolate
, we have:

2. Using the equation we rearranged in part 1, we can substitute given values:

3. We see from our equation in part 1 (
) that when
, the denominator of our fraction will be equal to 0. Since we cannot divide by 0, the velocity remains undefined and cannot be determined.
Answer:
20x + 17 = 77 --> Addition Property of Equality:
You are adding (Addition Property) 4x to both sides of the equal sign (Equality).
20x = 60 --> Subtraction Property of Equality:
You subtracted (Subtraction Property) 17 from both sides of the equal sign (Equality).
x = 3 --> Division Property of Equality:
You divided (Division Property) 20 from both sides of the equal sign (Equality) to completely isolate the variable x.
