The sequence is to multiply by -3.  Therefore, you want to multiply by -3 which gives you 108.  Since it is a negative by a positive the answer would be negative.  The next term would be -108.
        
             
        
        
        
Answer:
y=40-15x
Step-by-step explanation:
Let x represent the number of hours.
We have been given that Dudley travels 30 miles every 2 hours, so distance covered in each hour by Dudley would be:
.
Since Dudley travels 15 km per hour, so distance covered in x hours would be 15x.
We have been given that Dudley wants to cover 40 miles. So we can represent our given information in an equation as:
, where, y represents number of miles he has left to travel, after biking x hours.

Answer:
163.3m²
Step-by-step explanation:
area = Pi(r²)
r = d / 2
r = 12
12² = 144
144 x 3.14 = 452.16
diameter of bigger circle = 24 + 4 (2 on each side)
28 / 2 = 14
14² = 196
196 x 3.14 = 615.44
sidewalk = bigger - smaller
sidewalk = 615.44 - 452.16
sidewalk = 163.3
 
        
             
        
        
        
I'm pretty sure your answer is 17
