Answer:
B.
Step-by-step explanation:
This is vertical reflection, because reflections are made across vertical lines.
30 minutes / 3 miles = 10 minutes for 1 mile
7 miles * 10 minutes per mile = 70 minutes total to run 7 miles
9 1/8
4/8+5/8=9/8=1 1/8
5+3=8
8+1 1/8=9 1/8
Coefficient is the answer. A coefficient is what multiplies the variable, like 5X.
