Answer:
Step-by-step explanation:
If the jacket was discounted at 25%, that means that you get 25% off, right? What it also means is that you are still paying 75%. To get to the price of the jacket on sale, multiply the price of the jacket by 75% (as a decimal):
290(.75) = 217.50
That's the price of the jacket when it is 25% off the original price. If Arianna got an additional 10% off that price, that means she got 10% off but is still paying 90%. To get to the final price that she paid, multiply the sale price of the jacket by 90% (as a decimal):
217.50(.90) = 195.75
That's what she paid in the end for the jacket (i guess not counting tax...?)
Alrighty.
First we need to make them all simplified.
So simplified would be

times

times

.
Then we multiply the numerator and the denominator. The final answer is

Simplified is

Answer:
The answer is the option D 
Step-by-step explanation:
we know that
The triangles EDC and ABC are similar
then
The ratio of their corresponding sides is equal
so

substitute
