Answer: $12.50
Step-by-step explanation:
Sarah starts out with $100. She gave 3/4 of it away. 3/4 of 100 is 75. So, that means she gave $75 to her sister. she has $25 left but she gives half of the 25 to her friends. You would divide 25 by 2. since you have to split the 25 in half. she gave away $12.50 and she kept $12.50 for herself. So, she has $12.50 left after giving the money away.
P= 2w+2L
2(55)+2(110)=
110+220=330
The perimeter is 330 yards

The denominator of the rational expression 600/(x-4) is x-4.
We know x represents Sarah’s average speed. So x-4 will also represents the average speed. And x-4 represents 4 mph less than the average speed of Sarah, x.
Therefore, option a) is correct.
