Answer:
2 miles per a hour
Step-by-step explanation:
m=miles
h=hours
1/2m=1/4h
if you times both sides by 4 you will get
2m=h
First, we multiply the denominator to get to 9. That would be x3. We then do that to the top, and end up with the fraction 3/9, which is equivalent to 1/3.
Kelly's sister is x years old.
Kelly is 3 years younger than her sister, so Kelly is x - 3 years old.
The sum of their ages is x + x - 3 = 2x - 3.
The sum of their ages is 34, so
2x - 3 = 34
2x = 37
x = 18.5 Kelly's sister's age.
x - 3 = 18.5 - 3 = 15.5 Kelly's age.
Kelly's sister is 18.5 years old.
Kelly is 15.5 years old.
