The compact car has a range of 400 miles because 16x25. On the other hand the sedan has a range of 420 miles because of 21x20. Therefore they should get the sedan because it can travel farther.

Answer: The worm slithers 48 inches in an hour. The snail slithers 52 inches in an hour.
If we start by making both the races into equations we get 5w+4s=448 inch and 2w+3s=252 inch. If we then add both the equations together we get 7w+7s=700 inch. Then we divide it all to get 1w+1s=100 inch. Then we can subtract the second race from the first to get 3w+1s=196 inch. We now know that 2w=96 inch, and can therefor divide whit 2 to find out w=48. We can then figure out how fast the snail is moving by multiplying 48 whit w and dividing the answer by s.

\frac{3x - 2}{x^{2} - 2x - 3} - \frac{1}{x - 3} = \frac{3x  -2}{(x + 1)(x - 3)} - \frac{1}{x - 3} = \frac{3x - 2}{(x + 1)(x - 3)} - \frac{1(x + 1)}{(x + 1)(x - 3)} = \frac{3x - 2}{(x + 1)(x - 3)} - \frac{x + 1}{(x + 1)(x - 3)} = \frac{2x - 3}{(x + 1)(x - 3)}

Seperate the number 53 into 3 parts so that the second number is 3 less than the first number and the third number is twice the
irga5000 [103]
Hello,

Let a the first, b the second and c the third.
a+b+c=53
b=a/3
c=2a
==>a+a/3+2a=53
==>10a/3=53
==>a=15.9
c=2*a=2*15.9=31.8
b=a/3=15.9/3=5.3

Proof: a+b+c=15.9+5.3+31.8=53

The second number is 5.3
