First we have to setup system of equations for the given case.
Let x is the original number and y is the reverse three digit number.
Then,
x+y=665 Equation 1
x-y=297 Equation 2
Add both equations to get.
2x=962
Divide both sides by 2.
x=481
This is the original number. And reverse number is : 481+y=962
y=184
Here Hundredth digit is 4, and tenth digit is 8 which is 2 times of the hundredth digit.
Answer: Number is 481

Answer: 3.6
Step-by-step explanation: What i did was determined how many minutes are in a hour which are 60 minutes. so due to the fact that you're looking for the travel in (15) "minutes" I had to divide 54 by 15. Which gives you 3.6
10 more than 23 is 33 because 10 +23 = 33.
For this question, you need to decide whether to use sin cos or tan.
You have the hypotenuse and Ф but you need to find the opposite side.
For those reasons you would use sin, as it has all three in its triangle,
The equation for opposite = sinФ * hypotenuse
So sin49 * 12.38 = 9.3cm.
The answer is 9.3cm.
Hope this helps.
