<u>P = 2L + 2W</u>
Subtract 2L from each side: P - 2L = 2W
Divide each side by 2 : <em>(P - 2L) / 2 = W </em>
You would mutiple 22000 by 5 then divide that by .2 and that would be your answer
Riley has a total of,
8p + 7 + 2p + 5 or
10p + 12 dollars
Pam on the other hand has
(10p + 12) - 7p = 3p + 12 dollars
After giving half of this money to Riley, Pam will have
1.5p + 6 dollars
4p-19
You need to distribute the 5 first then the -2
you will get 10p-15-4-6p
then all you need to do is combine like terms to get 4p-19
So cost=50+75t
so 200=50+75t
subtract 50 from both sides
150=75t
divide both sides by 75
2=t
$200=2 hours
50+75t=cost
300=50+75t
subtract 50 from both sides
250=75t
divide both sides by 75
10/3=t=200 mins=3hours 20 mins=$300
