Henrietta solved a rational equation by multiplying both sides by 
.She did not find the least common multiple of the denominators .If she had find the least common denominator which is 3x(x+2) then the question can have been simplified in more simpler form.
Henrietta can have got rid of denominator and then use the distributive rule .
So the first option
A:She could use the least common multiple of the denominator is right
Using the midpoint formula we get:
(x,y)=(0+5/2, 0+12/2) or (5/2, 6) as the midpoint.
Answer:
D). 262.5 miles.
Step-by-step explanation:
The speed at which they are drawing apart = 60 + 45 = 105 mph.
So in 2.5 hours they wiil be
2.5 * 105
= 210 + 52.5
= 262.5 miles.
The sine of 1/2 the angle = 13 / 32
so this angle = 23.9695 degrees
Therefore the required angle = 2 * 23.9695 = 47.939 to 3 DP's.
