30 is the b in this equation which represents the number of miles she has already jogged. 6 represents the number of miles she jogs every day for x amount of days. x could be 5, in which case it would be represented as 6*5+30=60. But since we don't know what x is, it is just 6x+30.
Explanation: Since she plans to jog 6 miles PER DAY, we know we’ll be using a variable- x. So we know that we’ll be using 6x, but that leaves the original 30 miles. Since the 6x is also talking about miles, it’s a matter of addition. This brings us to the answer, 6x+30. I hope this helps!
Step-by-step explanation: So basically you are asking for the reciprocal and the reciprocal of 19/3 is 3/19. You just basically flip the fraction around.
