Answer:
171 miles
Step-by-step explanation:
distance = speed * time
in this case the speed is 57 miles per hour
the time is 3 hours
hence distance = 57 * 3
<u><em>= 171 miles</em></u>
57 x 3 = 171
1- B & C (Same answer and also I'm not that sure)
2- B: y = 8x (I'm sure of this ^^)
3- Option 3
4- 108 degrees
last one - 4/-2
two minus(-) becomes a plus(+)
9.01 maybe my math might be wrong
