1) 2.7*10=27 (total number of miles ran by everyone)
4*3=12 (to find how many miles not averaged, multiply)
27-12=15 (how many miles left over for the other 6 people to run)
15/6= 2.5 (your answer)
2. 80/400= .2 (E)
3. Given:
x-5/4=-9/5
Mulitply everything by 4 to cancle it out
x-5=-36/5
add 5 to both sides
x=-11/5
4. A
5.E
6.A
