Answer:
Carla has been running 7 miles each day for 13 days.
Step-by-step explanation:
Carla ran 3 miles on her first day, 5 miles on her second day and then 7 miles each day onward.
Let the number of days she ran 7 miles each day = x
Total distance run by Carla = 3 + 5 + 7(x)
                                              = 8 + 7x
If her log book shows that she has run total distance = 99 miles
Equation representing her total run will be,
8 + 7x = 99
7x = 99 - 8
7x = 91
x = 
x = 13 days
Therefore, Carla has been running 7 miles each day for 13 days.

Answer:
p^(-9) or 1/p^9
Step-by-step explanation:
Here we have:
   (5p)^(-7)
----------------
    (20p)^2
Let's temporarily remove the coefficient 5/20 and reduce it to 1/4.
then we have:
             1                             1                1
(1/4) -------------  = (1/4) -------------- = ------------
        p^7*p^2               p^(7 + 2)         p^9
 
        
             
        
        
        
Answer:
x=2 or x=3
Step-by-step explanation:
x^4 - 5x^3 + 7x^2 - 5x + 6 = 0
Step 1=Factor left side of equation.
(x-2) (x-3) (x^2 + 1) = 0
Step 2=Set factors equal to 0.
x-2 = 0 or x-3 = 0 or x^2 + 1 = 0.
Answer:x=2 or x=3
