Answer:
8.2
Step-by-step explanation:
We have been given that the ratio of hydrogen to oxygen atoms in water molecules is 2 to 1.
We can represent this information as: 
Let x be amount of moles of hydrogen atoms in water beaker. The proportion of hydrogen and oxygen moles will be same in water beaker.
Upon substituting our values in above proportion we will get,
Therefore, the moles of hydrogen atoms in water beaker will be 8.2.
Answer:3 1/6
Step-by-step explanation:
The did not combine like terms correctly.
Step SHOULD'VE went like this:
20-26=-6 & -34+60=26
-6+9=3
3=26
Divide!
3÷3=0 ⇒26÷3=8.6666.....
or (rounded)
the answer would be 8.7
Step-by-step explanation:
slope of AB = y2 -y1/x2 -x1 =14 -(-2)/1-9
= 14 +2 /1 -9
= 16/-8
= -2
slope of CD = -14 -(-10)/8 -6 = -14 +10 /2
-4/2 = -2
since slope of AB = CD
(The lines are parallel to each other)
Answer:
D. There are infinitely many solutions
Step-by-step explanation:
Solving the second equation for y gives you the first equation. This is a dependent system. Any solution of one equation is also a solution to the other one. There are infinitely many solutions.
