Step-by-step explanation:
A simple cross multipilcation
It says it has gone down 85%, so only 15% is left.
120 liters is 15% of the original sum.
120 liters 15%
x= 100%
120*100/15 = 800 liters
(x-0) squared + (y+8) squared =100 sorry i don’t know how to do the squared sign on my phone

Answer:
17
Step-by-step explanation:
First, you can change the equation to 12 1/2 + 4 1/2, as subtracting a negative number is actually adding it. Then, if easier, the mixed numbers can be changed to improper fractions -- 12 1/2 = 25/2 and 4 1/2 = 9/2. Then add; 25/2 + 9/2 = 34/2, and 34 divided by 2 is 17.
