Answer: C
Step-by-step explanation:
You need to substitute x for 2.5. After that, multiply 101 and 2.5 to get 252.5. Then, add 252.5 and 207.85 to get 460.35.
To answer this, you need to get "d" on one side by itself. To do this, add 8 to both sides of the equation.
d- 8 + 8 = 5 + 8
-8 and +8 cancel out leaving:
d = 13
Your answer is d = 13
216 sequences are possible
1. x=-3 y=4 2. x=5/2 y=15/2 3. x=9/5 y=-36/5 4. x=-2 y=1
Since they are moving in opposite directions, this is the same as Amy staying still and Erica biking at 10 meters per second away from her.
To travel 1km = 1000m at 10 meters per second, you need 1000/10 = 100 seconds.
