Answer:
it's 20
Step-by-step explanation:
Original Price: $45
Current price: 45 x 20% - 45
45 x 20% = 9
Always add/subtract by the original number, but since we're finding the price 'decrease', you subtract by the original number.
45 - 9 = 36
Answer: $36
Answer: 3:1
Step-by-step explanation:
From the question, we are informed that a gear ratio is the ratio of the teeth on the front sprocket and the teeth on the rear sprocket.
We are further told that the bike has 36 teeth on the front sprocket and 12 teeth on the rear sprocket.
Based on the explanation given in the question, the gear ratio for the bike would be the ratio of 36 to 12. This will be:
= 36:12
Since 12 is a common factor. It can be further reduced to 3:1.
Therefore, the gear ratio is 3:1
Answer: Travis studied Spanish for 2.5 hours.
Step-by-step explanation:
1. First, we have to make our equation. Since it DID state that he studied x hours EACH for Spanish, English, and Social Studies, we could just make that 3x.
So,
3x + 1.5 + 2.25= 11.25
3x + 3.75= 11.25
-3.75 -3.75
3x/3=7.50/3
x=2.5
