We will say that the eastbound cyclist is going x mph. This means that the westbound cyclist is going x+3 mph.
They are both cycling for 6 hours and end up 162 miles apart.
Distance=rate*time
6x+6(x+3)=162
6x+6x+18+162
12x=144
x=12
So, the eastbound cyclist is going 12 mph.
Remember the westbound cyclist is going 3 mph faster, so s/he is going 15 mph.
Hope this helps!!
Answer:
just graph the problem so that you can answer
Assuming he spends all the $24 on renting DVD's we can simply divide the money he has available with the price of each DVD in order to know how many he can buy.
$24/$4 = 6
Jack can rent a maximum of 6 DVD's
1) Turn -2x to a sum or difference
- x2 + 4x - 6x -24
2) Factor out the x
- x(x + 4) - 6x -24
3) Factor out the 6
- x(x + 4) - 6(x + 4)
4) Factor out x + 4
- (x + 4)(x - 6)
FINAL ANSWER
(x + 4)(x - 6)
