20 represents how much time practicing in running has reduced her run time, and dividing by 4 weeks show the amount of seconds lowered per week (5 seconds).
Answer:
25 = x
Step-by-step explanation:
The angles are vertical angles and vertical angles are equal
5x+15 = 6x -10
Subtract 5x from each side
5x-5x+15 = 6x-5x -10
15 = x - 10
Add 10 to each side
15+10 = x-10+10
25 = x
Zero of divisor (x+2) is -2
Now putting the value of x as -2,
