Answer:
Step-by-step explanation:
L=2W
P=2(L+W), using L=2W this becomes
P=2(2W+W)
P=2(3W)
P=6W, given P=150
6W=150
W=25, and since L=2W
L=50 so
L=50ft and W=25ft
solution:
The variable is discrete because it is countable.
The number5 of lightning strikes in a city in one year is countable value.
So, it is discrete
H+20=35-4H
first, combine your like terms, which are the Hs
add the 4H to both sides, and you will get
5H+20=35
now subtract 20 from both sides, that will cancel out the 20 on the left and leave you with
5H=15
finally, divide both sides by 5 and you will get H=3.
I believe it would be .21m. So for example.The memory stick is sold normally for $14, so to plug it into the equation it would be: .21(14), which gives you the discount of $2.94. Subtract that amount from the original price, and that gives you the sale price. .21(14)=2.94 14-2.94=11.06~~~~~Sale price
