Hello,
you may not used what you are going to prove in a proof (la thèse)
Answer:
The total members in the Spanish Club = 50
Step-by-step explanation:
Let the total members in the Spanish Club = x
Now, number of girls in the club = 30
Three-fifths of the members are girls.
⇒ 
of total members x = 30
or, 
Now, solving for x, we get:
or, x = 50
Hence,the total members in the Spanish Club = 50
So if the dress is 25% off, that means you are paying 75% of the original price.
sale price = original price x 0.75
225 = original price x 0.75
divide both sides by 0.75 to isolate original price
225/0.75 = (original price x 0.75)/0.75
300 = original price
Estimation is a way to find out the approximation of something. It is important because it kinda leads to what the correct answer is and it is needed because you can estimate how much a bill would be or you could estimate how much is the area or size of something. It's very important...
3r=10+5s
3*10=10+5s
30=10+5s
30-10=5s
20=5s
s=4
r=10
