Which of the following would not be a line in solving the equation: 7x-8-5x = 52
12x = 60
12x = 44
12x - 8 = 52
x = 5

Step-by-step explanation:

Step-by-step explanation:

Let's actually solve the equation.  By doing so we should readily see which of the given equatins are not part of the solution.

7x - 8 - 5x = 52 becomes 2x - 8 = 52 if we consolidate the x terms.  Next, we consolidate the constant terms on the right, obtaining 2x = 60.

Then x = 30 is the solution.

12x = 60 would not be part of the solution.

12x = 44 would not either.

12x - 8 = 52 would not either.

x = 5 would not be part of the solution.

Again:  The solution is x = 30.

5 miles/hour

Step-by-step explanation:

the distance is the length of the track which is given as 1/4 of a mile. she completes each lap in 1/20 of an hour so divide the distance by the time taken to go around the distance
