Answer:
- 3 and 5 if "." marks thousands
- 2, 3, 5, 6 if "." is a decimal point
Step-by-step explanation:
The number 2145 is not even, so will not be divisible by 2 or 6. It ends in 5 so is divisible by 5. Its sum of digits is 12, which is divisible by 3, so the number is divisible by 3.
2145 is divisible by 3 and 5.
2.145 is divisible by all of these numbers:
2.145/2 = 1.0725
2.145/6 = 0.3575
2.145/5 = 0.429
2.145/3 = 0.715
_____
Here, we take the mixed number to be divisible if the decimal representation of the quotient is a terminating decimal fraction.
(12.65) is your total answer because 20/100 x63.25 gives you 12.65
Answer: 5
Step-by-step explanation:
8+2=10
10/2=5
Answer: Choice C) y = 30/x
Inverse variation equations are of the form y = k/x. In this case, k = 30. We can rearrange the format to get x*y = k after multiplying both sides by x. So y = 30/x can be turned into x*y = 30.
Call the price of the bike before mark up 'x', then we have:
x + 0.25x = 210
1.25x = 210
x = 168
Therefore, the bike cost $168 before 25% price increase.
