Answer:
a) 7 weeks b) George's
Step-by-step explanation:
Sally's score can be modeled by 10x+850.
George's score can be modeled by 50x+570.
We can set them equal to each other to see when they intersect.
10x+850=50x+570
40x=280
x=7
If George overtakes her in the 7th week, of course he'll have the higher score in 12 weeks.

m = -11/6
Step-by-step explanation:
5m -2(m + 2) = -(3m +15)
5m - 2m - 4 = -3m - 15
3m + 3m = -15 + 4
6m = -11
m = -11/6
True because if you did 180°-270° it would be in quadrant 3 or it could be on quadrant 2 because quadrant 2 is 90-180
