The flag pole is 20 feet tall with an 8 foot shadow.
The tree is X feet tall with a 12 foot shadow.
20/8 = X/12
Cross multiply:
20 * 12 / 8*X
240 = 8x
Divide both sides by 8:
x = 240/8
x = 30
The tree is 30 feet tall.
First isolate x by multiplying by x on both sides. It will look like this:
(2/3)x=1.2
Then devise by (2/3) on both sides to get:
x= 1.2/(2/3)
The easiest way to get this is plug that into a calculator and get the answer:
x=1.8
Answer:
All we do is do 3.5 x 5 to get 17.5 water!
Step-by-step explanation:

Subtraction of functions has the property:
f={(−4,−1),(1,1),(−3,−2),(−5,2)} has (1,1) means that f maps 1 to 1, therefore f(1) = 1
g={(1,1),(2,−3),(3,−1)} has (1,1), means that g maps 1 to 1, therefore g(1)=1
As a Result, since (f−g)(1) = f(1) - g(1), we have (f−g)(1) = 1-1=0
