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:
63 yards
Step-by-step explanation:
Based on the description, you can make a rectangle with the sides 20 yards and 60 yards. You then draw a diagonal line (doesn't matter which one), and you use the pythagorean theorem (a^2+b^2=c^2). Thus, you get 20^2+60^2=60^2, so 400+3600=c^2, then \sqrt{4000}
Which gives the value of 63.24 rounding to 63 yards
