That's a 33% increase.
I calculated this using the formula:

Where n = the new value (16 in your question), o = the old value (12 in your question) and the result is outputted as a percent increase. You can check that this is correct by finding 33% of 12, adding the result to 12, and checking that the result equals your "new" number.
Note that 33% is only an approximation as your question requires a number rounded to the nearest whole.
U do 5 times 30 and get 150 then take 15 times 50 and get 750 last take 750 plus 150 and u get 900 cm
Answer:
Explain what you mean please :)?
Step-by-step explanation:
To subtract fractions, we need a common denominator.

-

the common denominator will be (y-2)(y+3)



The answer above will be the simplified form.
The given equations are

TO solve for p and w, we can use elimination method. And the first step is to eliminate p by adding both equations .
So out of the given options, correct option is the first option .
