Let us say the price of a table is 
and a price of a chair 
. Using this terminology we can say that the cost of 2 chairs and 5 tables is 
. We have a second equation though, 
from a table being 30 more than the price of a chair. Using this we can solve the system of equations. I think substitution is the quickest way to do this. Plug x from our second equation into the first equation.
This will simplify to the price of a chair is Rs 320. And add Rs 30 to that and we can find that the price of a table is Rs 350.
It is always good to check. So go ahead and check 
to see that the first equation works (we know the second equation works just by eyeballing. And it looks like the cost is Rs 2300! Hooray!
Answer:
Step-by-step explanation:
You want to find out how how 1/12 of a tsp go into 3/4 of a tsp so.......
You do 3/4 divided by 1/12 but when dividing fractions you flip over the second fraction and change the division operation to a multiplication operator so....
It will 3/4 x 12/1 and this will give you 36/4
36 divided by 4 is 9
So....
Kathy can bake 9 cakes.

To determine the thickness of the film, we assume the shape of the film is in a form of cylinder where the thickness is equal to the height. The volume of a cylinder is expressed as:
V = pi (r^2) h
We calculate as follows:
0.23 = pi (10^2) (h)
h = 0.0007 cm
