Answer:
22 11/16 or 22.68
Step-by-step explanation:
Turn the mixed numbers to fractions

Then multiply both Numerators
11 x 33=363
Also do the same to the Denominators
2 x 8=16
You get 
Simplify and it becomes 22 11/16 or 22.68
It would be 7/10 because since 10/10 is the Earth, and 3/10 is water, 10-3 is 7.

Answer:
"Commutative property of addition and of multiplication"
Step-by-step explanation:
This is the "commutative property" of addition and of multiplication. That as its name indicates tells us for additions, that if we add A + B, or B + A, we should get the same result. Similarly, the "commutative property" of multiplication tells us that if we perform the product A * B we should get the same answer as if we perform the product: B * A.
So 2x+12=5x-9
you want all of the unknowns on one side and all of the known values on the other or
subtract 2x from both sides
12=3x-9
add 9 to both sides
21=3x
divide both sides by 3
7=x
