The rate of how many projects Taylor can complete can be modeled at x/6 and Brianne can be modelled as x/8. So, by combining the functions and setting equal to 1, you can solve. 

x/6 + x/8 = 1

You have to give common demoninators

4x/24 + 3x/24 = 1

Then add together and cross multiply. Giving you an answer of 24/7 or roughly 3.43 hours when rounded to the nearest hundredth.

What is the answer is think it is a but I don't know. plz help.
Papessa [141]
Hi there!

The answer is actually D.

Since both the numerator and the denominator multiplied by 3 is 3/9, the answer would be 9.

-1 × 3 = -3
-3 × 3 = -9

Since a negative number times a positive number is a negative number, the correct answer would be D.

Hope this helps!
