1. Write an equation comparing the group rate to the sum of the individual
rates. How should the group rate and the sum of the individual parts
compare? Use parts (b) and (c) to help you write the equation.
2. Find the LCD of 1/3 = 1/x + 1/2 + 1/3
3. Solve the equation and determine how long it will take Molli to paint the
room alone.
please help, god bless you and thank you in advance.
1/3 = 1/x + 1/2 + 1/3
the LCD is 6x, so multiply each term by 6x
2x = 6 + 3x + 2x
3x= -6
x = -2
you did not provide a definition of x, so it is not possible to tell
if that answer is valid.
