first combine like terms so 2n + 7n which is 9n
so 9n + 7 = 13 + 3n + 8n
then combine on other side so 9n + 7 = 13 + 11n
then subtract 7 to 13 so 6
sp 9n + 6 = 11n
then subtract 9 to the other side so 2n
6 = 2n then divide all by 2
n= 3
It would be 7lbs, you divide the total amount by the amount per pound and you get the weight.
Answer:
5 Outer and 1 lone pair
Step-by-step explanation:
A square pyramidal shape results when one of the bonds of an octahedron structure is occupied by a lone pair.
Hence there are 5 bonded atoms and one lone pair. The hybridization about the central atom is
.
One of the most common example is Xenon tetraflouride.
. Looking at its structure we can see that it has 5 pairs of outer atoms and one lone pair. With its coordination number 5. The shape of the orbitals is octahedral.
Answer:

-8 to the power of 0 = 1
(Anything to the power of 0 = 1)
and 6 to the power of -1 = 1/6
( Any number to the power of a negative number will become a fraction)
Example.

So is will be 1/6 over 1
Which gives you your final answer.
Answer:
No.
Step-by-step explanation:
The ratio of the lengths of the vertical sides from A to B is 2/4 which equals 1/2.
The ratio of the lengths of the horizontal sides of A to B is 4/11.
Since 4/11 is not equal to 1/2, figure B is not a scale copy of figure A.
