Answer:
D 5x + 13 = 12
Step-by-step explanation:
3 + 5(x + 2) = 12
3 + 5x + 10 = 12
5x = -1
x = -1/5
D) 5x + 13 = 12
5x = 12 - 13 = -1
x = -1/5
1. Find the distance Sonya traveled:
20-8=12
12x1000feet=12000feet
2. Find the time it took Sonya to travel this distance:
Starting time: 3:10
Finish time: 3:14
Difference= 4min
3. Use the speed formula: S=D/T
S=12000feet/4min
S=3000feet/min
