Answer:
y=13/11+17x/11 (these are fractions)
Step-by-step explanation:
Move all terms that don't contain
y
to the right side and solve.
Answer:
90.
Step-by-step explanation:
We have two lines of code:
y ← x + x + x + x + x
z ← y + y + y
and, x=6 before the execution. Then, when the program starts to run we obtain:
y ← 6 + 6 + 6 + 6 + 6
y ← 30
z ← 30+30+30
z ← 90.
Then, the value of z after excecution is 90.
Answer:
1. 24
2. 6
3. No
Step-by-step explanation:
The formula for cyclic alkene is
, so if it has 12 carbon atoms, it will have double the amount of hydrogen atoms, therefore, 24 hydrogen atoms.
The same works in reverse. If we have 12 hydrogen atoms in this, then there will be half the amount of carbon atoms, therefore 6.
Since the relationship between Carbon and Hydrogen here is double and half, odd numbers can't be divided by 2 and end up with a whole number, so an odd number of hydrogen atoms is not possible.
Hope this helped!
If you're talking about the second part of the question where it asks you which facts you included in your answer, you can choose any of them and it will be counted right.
