A)
Kim's age=k
Sister's age=s
k=2s
k+s=36
b)
k=2s
k+s=36
k=36-s
2s=36-s
3s=36
s=12
12*2=24

Answer: Nicole rented the scooter for 10 days.
Step-by-step explanation:
50 + 25 = 75 (Day 1)
75 + 25 = 100 (Day 2)
100 + 25 = 125 (Day 3)
125 + 25 = 150 (Day 4)
150 + 25 = 175 (Day 5)
175 + 25 = 200 (Day 6)
200 + 25 = 225 (Day 7)
225 + 25 = 250 (Day 8)
250 + 25 = 275 (Day 9)
275 + 25 = 300 (Day 10)
| 4x - 3| - 5 = 4
| 4x - 3| = 9
4x - 3 = 9 -(4x - 3) = 9
4x = 12 -4x + 3 = 9
x = 3 -4x = 6
x = -6/4 or -1.5
solution to equation 1 : x = 3 and x = -1.5
|2x + 3| + 8 = 3
| 2x + 3| = - 5....no solution because an absolute value cannot equal a negative number
(9.83-9.74)=0.09
(0.09/9.83)(100)=0.9155645982%
