Answer:
3/4 times 18= 13.5
31.5-13.5=18
It cost 18 dollars for the skirt with a discount.
It cost 13.5 for the blouse as opposed to the original price of 18 dollars.
18(skirt)+13.5(blouse)=31.5
If you set up a proportion to find the original price of the skirt you will get the answer.
18/x=75/100
75x=18 times 100
75x=1800
75x/75=1800/75
x=24
The original price of the skirt is 24 dollars.
Step-by-step explanation:
Hello! To find the formula for Celsius to Fahrenheit, we just basically find the inverses of what's in the problem. The multiplicative inverse of 5/9 is 9/5. The opposite of f - 32 is c + 32. The formula is 9/5c + 32. Even on the internet, it confirms that the formula is 9/5 and then add 32. The answer is B.
The answer is d
Domain is just all x values
Answer:
around 13
Step-by-step explanation:
First, we are going to add

from both sides of the equation:


Next, we are going to use the trig identity:

to rewrite our expression:



Finally, using our unitary circle, we can infer that

from 0 to

when

and

We can conclude that the solutions of the equation <span>cos (x) tan (x) -1/2=0 over the interval [0,2π] are: </span>
