b) Distance = Speed x Time
8.5 miles per hour x 5.5h = 46.75 miles
1. 12=x+3 12-3=9 now try 9+3 that is 12 so x=9
2. b+0.6=-1 -1-0.6=-1.6 -1.6+0.6=-1 b=-1.6
3. a=-9
4. x=-39 I believe
5. a=-4.3
One way is to turn them into fractions and simplify them then see if they are equal exg
8:4 and 6:3
turn into fractions
8/4 and 6/3
2/1 and 2/1
equal
There are 6 balls to every box (a ratio of 6 to 1). Therefore, when there are 78 balls, there are 13 boxes.
Use the chain rule.
Let u = 25sin²(x), such that dy/dx = dy/du · du/dx
