Anita first rode her bike 5 blocks to the east.
She then rode twice as many blocks west. 5*2=10. She rode 10 block west. Subtract 10 from 5: 5-10=-5
She finally rode 8 blocks back east. Add 8 to -5: -5+8=3.
Anita is three blocks east from home.
I think that you have to divide.
Answer:
Odd integers are always one more that an even integer:
1st: 2n+1
2nd: 2n+3
Step-by-step explanation:
14n+7 = 10n+15
4n = 8
n = 2
------------
1st: 2n+1 = 5
2nd: 2n+3 = 7
7x=5*(x+2)
7x=5x+10
7x-5x=10
2x=10
x=5
