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.
-20 28/35, -20, 20 28/40, 20 27/30
- the negative numbers will always be less than the positive numbers, so those will be first. Now you have to find the BIGGEST negative number, that’s is worth less than the smaller negative number, because negatives are like opposites of positives. So the bigger negative number is first, then the next negative number. Now you just find the smallest positive number to the biggest positive number.
$11 is the independent and the $30 is dependent because to get the $30 a week, it depends on that $11 per house.
