Answer:
(f+g)(x)=2x+1+5 - x
(f+g)(x)=x + 6
(f - g)(x)= 2x + 1 - (5- x )
(f - g)(x)= 3x - 4
Monday: 3 1/4 miles
Tuesday: (3 1/4)(2/3) = 2 1/6 miles
Wednesday: (2 1/6)(2) = 4 1/3 miles
Thursday: (4 1/3)(3/4) = 3 1/4 miles
Add them all up: 13 miles
She has not reached her goal, she needs to ride her bike 2 more miles to reach her goal.
To find the lowest common denominator between the fractions, what you need to do is simply write out the multiples of both 3 and 5 and find what multiple is common between both:
3,6,9,12,15
5,10,15
The multiple that is common and is the lowest in both would be 15.
The solution thus is B.15, it is the LCD for the fractions of 2/3 and 4/5.
