Answer:
Step-by-step explanation:
use the equation: y =50x-350 where x is the number of hours driving
hrs
1 50 300
2 100 250
3 150 200
5 250 100
7 350 0
-12.405=-12 405/1000= 12 81/200
You need to get L by itself. Keep in mind with equality problems that what you do to one side, you must do to the other.
Let me break it down for you.
P=2L+2W, -2w from both sides.
P-2W=2L, now divide the other side by 2.
1/2P-W=L
