It is not possible for Jackie to have spent 45 minutes dancing if she runs and dances for a total of exactly 55 minutes and dances for 25 minutes longer than she runs.

System of equations

These are equations that is made of unknown variables.

Let the time she dances be x

Let the time she runs be y

If Jackie runs and dances for a total of 55 minutes every day, the;

x + y = 55 ............ 1

If She dances for 25 minutes longer than she runs, then;

x = y + 25 ............. 2

The pair of equation are x + y = 55 and x = y + 25

Substitute 2 into 1

y + 25 + y= 55

2y .= 30

y = 15

He spent 15 minutes running everyday

x = 55 - 15

x= 40minutes

It is not possible for Jackie to have spent 45 minutes dancing if she runs and dances for a total of exactly 55 minutes and dances for 25 minutes longer than she runs.
