Now let's do $1.25 divided by 10.
$
divided by $

Now let's do
times 
x 
Now let's add 7.5 to 0.5

Answer:
The most straightforward way to obtain the expression for cos(2x) is by using the "cosine of the sum" formula: cos(x + y) = cosx*cosy - sinx*siny. cos(2x) = cos² (x) - (1 - cos²(x)) = 2cos²(x) - 1. = 2cos²(x) - 1.
Step-by-step explanation:
Answer:
none, because without the letters and numbers.the plate number can not be identify or formed
This is a percent problem which means
You take the amount that has been completed over the total amount. You then multiply it by 100%
30/120*100=25%
Using a system of equations, it is found that:
- There are 8 chickens in the yard.
- There are 16 pigs in the yard.
-----------------------------------------
This question is solved using a system of equations. I am going to say that:
- x is the number of chickens.
-----------------------------------------
- A chicken has 1 head, as do a pig.
- There are 24 heads.
Thus:

-----------------------------------------
- A chicken has 2 feet.
- A pig has 4 feet.
- In total, there are 80 feet.
Thus:

-----------------------------------------
Number of chicken:
Since 






There are 8 chickens in the yard.
-----------------------------------------
Number of pigs:

There are 16 pigs in the yard.
