someone please help me . i really need to get this done soon
well actually im thinking its 6/8 but idk
In one hour Michelle, working alone, can complete 1/6 of the work. In one hour Nancy, working alone, can complete 1/3 of the work. Therefore if they work together for one hour they can complete 1/6 + 1/3 =1/2 of the work. Can you now see how many hours they would take to do the job when working together?
so is it 2?
Yes, 2 hours is correct.
thank you can you possibly help me with another?
You're welcome. I'll try to help.
Which of the following expressions is the conjugate of a complex number with 2 as the real part and 3i as the imaginary part? 2 + 3i 2 − 3i 3i + 2 3i − 2 I'm thinking it's 3i+2
|dw:1438557699594:dw| The above example might help you. Note the reversal of sign.
so would it be 3i+2?
